So the inverse of: 2x+3 is: (y−3)/2The inverse is usually shown by putting a little "-1" after the function name, like this:f-1(y)We say "f inverse of y"So, the inverse of f(x) = 2x+3 is written:f-1(y) = (y-3)/2...

Q.4. What is the inverse of the function f(x)=x+42x–5?Ans:Step 1: We have to substitute f(x) with y:y=x+42x–5Step 2: We swap the variables x and y:x=y+42y–5Step 3: We solve for y in the equation from step 2:x(2y–5)=y+4⇒2xy–5x=y+42xy–y=5x+4y(2x...
What is the inverse of y = -x?The Inverse Process of a Function:The inverse function is a new function formed by the reversed process of the function. For this process, we have to exchange the symbols of the independent and dependent variables in the original function....
2. Interchange the variables x and y . 3. Solve for • example : Find the inverse of y = 3x + 2 1. y = 3x + 2 2. x = 3y + 2 ( interchange x and y ) 3. ( solve for ) So, • example : Find the inverse of f (x) = 4 − 2x so, • Does every function...

In order to find the inverse function, we have to first interchange the variables x and y. After interchanging the variables, we need to solve for y. Lastly, we need to simplify.Answer and Explanation: We are given the function y=2x. We want to find the inverse of the fu...
Consider the following example: The graphs of a function {eq}f(x)=log_2(2x){/eq} and its inverse {eq}2^{x-1}{/eq} are drawn on the same XY plane. It can be observed that they are symmetric about the line {eq}y=x{/eq}. The Graph of a Log function and its InverseLesson...
