Use a graph of f(x) to determine the value of f(n), where n is a specific xvalueTable of Contents0000 Finding the value of f(2) from a graph of f(x)002Graph the following function {eq}f(x) = 4^x {/eq} Exponential Functions Exponential functions are the ones in which the variable of interest is the exponent of some other termF ( x) = x2 A function transformation takes whatever is the basic function f (x) and then "transforms" it (or "translates" it), which is a fancy way of saying that you change the formula a bit and thereby move the graph around For instance, the graph for y = x2 3 looks like this This is three units higher than the basic quadratic, f (x) = x2

Y=f(x) graph
Y=f(x) graph-Explanation In the relation , there are many values of that can be paired with more than one value of for example, To demonstrate that is a function of in the other examples, we solve each for can be rewritten as can be rewritten as can be rewritten as need not be rewrittenPurplemath The last two easy transformations involve flipping functions upside down (flipping them around the xaxis), and mirroring them in the yaxis The first, flipping upside down, is found by taking the negative of the original function;
Absolute value of an integerINTERPRETING GRAPHS OF f(x)The graph of the function f (x) is shown belowAccording to this graph we havef'a is (positive, equal to zero, or negative)f'b is (positive, equal to zero, or negative)f
For every value of x, y takes the value it would have at kx It is the graph of y = f(x) stretched by a factor of 1/k on the xaxisThe output f (x) is sometimes given an additional name y by y = f (x) The example that comes to mind is the square root function on your calculator The name of the function is \sqrt {\;\;} and we usually write the function as f (x) = \sqrt {x} On my calculator I input x for example by pressing 2 then 5 Then I invoke the function by pressingOn the graph of a line, the slope is a constant The tangent line is just the line itself So f' would just be a horizontal line For instance, if f (x) = 5x 1, then the slope is just 5 everywhere, so f' (x) = 5

C < 0 moves it down We can move it left or right by adding a constant to the xvalue g(x) = (x · In order to find what value (x) makes f (x) undefined, we must set the denominator equal to 0, and then solve for x f (x)=3/ (x2); · The graph of #f(x)=x^2# is called a "Parabola" It looks like this One of the ways to graph this is to use plug in a few xvalues and get an idea of the shape Since the x values keep getting squared, there is an exponential increase on either side of the yaxis
· Gió Dec 14, 14 This function is a constant so that for every value of x has always the same value of y, that is 4 A general straight line has the following form as a function y = f (x) = axb where a is the slope of the line and b the intercept with the y axis Now your function has the form f (x) = 0x 4CH11 Functions and Their Graphs Ex36數學系卡安很閒 所以決定拯救沒辦法用slader和chegg的莘莘學子To find f(x) you delete the decimal or fractional portion of x, leavingAbout Beyond simple math and grouping (like "(x2)(x4)"), there are some functions you can use as well Look below to see them all They are mostly standard functions written as you might expect
We set the denominator,which is x2, to 0 (x2=0, which is x=2) When we set the denominator of g (x) equal to 0, we get x=0 So x cannot be equal to 2 or 0 Please click on the image for a better understandingReflections of graphs Graphs can be reflected in either the \ (x\) or \ (y\) axes Reflections in the xaxis If \ (f (x) = x^2\), then \ (f (x) = (x^2)\)Let us start with a function, in this case it is f(x) = x 2, but it could be anything f(x) = x 2 Here are some simple things we can do to move or scale it on the graph We can move it up or down by adding a constant to the yvalue g(x) = x 2 C Note to move the line down, we use a negative value for C C > 0 moves it up;

Functions & Graphing Calculator \square!Mathf(x)=x/math Function is giving the absolute value of mathx/math whether mathx/math is positive or negative See the y axis of graph which is mathf(x)/math against mathx/math, as x axis It shows y axis values or mathf(x · To sketch y = 1/f(x) This should be obvious but note that the sign of f(x) is the same sign as 1/f(x) So for a given domain, no part of the graph of f(x) should suddenly switch to the other side of the xaxis when graphing 1/f(x)
Graph Transformations A transformation is something that is done to a graph/function that causes it to change in some way This topic is about the effects that changing a function has on its graph There are two types of transformation translations and reflections, giving 4 key skills you must be familiar with Throughout this topic, we will use the notation f(x) to refer to a function andFirst graph f(x) Derivative Integral C Blue 1 Blue 2 Blue 3 Blue 4 Blue 5 Blue 6 Red 1 Red 2 Red 3 Red 4 Yellow 1 Yellow 2 Green 1 Green 2 Green 3 Green 4 Green 5 Green 6 Black Grey 1 Grey 2 Grey 3 Grey 4 White Orange Turquoise Violet 1 Violet 2 Violet 3 Violet 4 Violet 5 Violet 6 Violet 7 Purple Brown 1 Brown 2 Brown 3 Cyan Transp Self 1 Self 2 Self 3The graph of the function is the set of all points latex\left(x,y\right)/latex in the plane that satisfies the equation latexy=f\left(x\right)/latex If the function is defined for only a few input values, then the graph of the function is only a few points, where the x coordinate of each point is an input value and the y coordinate of each point is the corresponding output value
