f(x) = x^4 has an inverse but it is not a function becaues f it is not a one to one. Use the graphing calculator above to graph each of the functions below and its inverse and determine whether the inverse (red) is a function or not and give an explanation. Find a formula for the graph of the inverse of f. Is the graph of of the inverse (in red) that of a function? If it is, it has to be the graph of the inverse of f. Enter x^3 - 1 in the editing window, which means f(x) = x^3 - 1, and press enter. Is the graph of of the inverse (in red) that of a function? If it is not a function, is f a one to one function? Enter x^2 in the editing window, which means f(x) = x^2, and press "Plot f(x) and Its Inverse". Find, analytically, the inverse function of f(x) = sqrt(x) including the domain and compare it to the graph obtained. Is the graph of the reversed pairs (in red) that of a function? If it is the graph of a function, it is the inverse function of f(x) = sqrt(x). Enter sqrt(x) in the editing window of the calculator, which means f(x) = sqrt(x), and press "Plot f(x) and Its Inverse". )and explore this property of reflection of the graphs of f and its inverse. Keep - as the lower bound but change the upper bound from to 2. Tap the down-arrow on the left of the input field. Due to the definition of the inverse function, we can easily note that the graphs of f (blue) and its inverse (red) are reflection of each other on the line y = x.Įnter different functions (x^3, x^2. Sketch the graph of each piece-wise function below. #PIECEWISE GRAPHING CALCULATOR DOWNLOAD#
Hover the mousse cursor on the top right of the graph to have the option of download the graph as a png file. Hover the mousse cursor over the graph to trace the coordinates. The variable in the expression of the function is the small letter x. Three graphs are displayed: the graph of function f (blue) that you input, the line y = x (black), and the graph (red) of the inverse.

How to Use Inverse Functions Graphing CalculatorĮnter a formula for function f (2x - 1 for example) and press "Plot f(x) and Its Inverse".
If needed, Free graph paper is available. If function f is not a one to one, the inverse is a relation but not a function. If function f is a one-to-one function, the graph of the inverse is that of a function.
The calculator will use the best method available so try out a lot of different types of problems. The Limit Calculator supports find a limit as x approaches any number including infinity. The inverse of a function may or may not be a function. Step 1: Enter the limit you want to find into the editor or submit the example problem. If (a, f(a)) is a point on the graph of f then the point (f(a), a) is a point on the graph of the inverse of f. The graph of the inverse of f is fomed by reversing the ordered pairs corresponding to all points on the graph (blue) of a function f. An online graphing calculator to draw the graph of function f (in blue) and its inverse (in red).
