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 \(f(x) = \frac{{x + 4}}{{2x – 5}}\)?Ans:Step 1: We have to substitute \(f(x)\) with \(y\):\(y = \frac{{x + 4}}{{2x – 5}}\)Step 2: We swap the variables \(x\) and \(y\):\(x = \frac{{y + 4}}{{2y ...
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...
