I'll use this to find the domain and range of my inverse. Here's the algebra for finding that inverse, starting with the original function: I multiply the denominator up to the left-hand side of the equation: y(x − 5) = −2 I take the y through the parentheses: xy − 5y...
How to Find the Inverse of a Rational Function Example 1 Let {eq}f(x) = \dfrac{6}{x+2} {/eq}. Find the inverse. Step 1:To determine whether the given function has an inverse, we graph it, and perform the horizontal line test. ...
FAQ: How to Expand the Inverse Function of a Given Function? How do you find the inverse of a function? To find the inverse of a function, you can switch the x and y variables and then solve for y. The resulting equation will be the inverse function....
Suppose you are asked to find the inverse of the function given this graph: Note that I have NOT told you what that function is. To get started finding the inverse, draw the reflection line: (It would be a good idea to use a ruler for this; you'll want to be neat.) ...
Inverse Functions: Logarithm If we have a function described by a form {eq}y = f(x) {/eq} and we wish to find its inverse function, our goal is to express the independent variable {eq}x {/eq} in terms of the dependent variable {eq}y {/eq}. The resultant function {eq}x = f...
I need to find inverse function of: Here is as near as I could get to isolating x: I used the solve function on my calculator and the inverse I got I entered into a graphing window: Now what I want to know is how do you get the red function out of the blue one? I mean, how...

So, the period for both cosine and sine function is 2pi(360). You can also check the period of sine or cosine function by adding 2pi(360) to any angle and you'll get the same result for the cosine for the sine of that angle. Since, Cosine(90 degree)=0 also, cosine (90+...
