Question

which function below is the inverse of f(x)=3x+5
7

Answer 1

You have a function y = 3x + 5.

To find the inverse, interchange x with y, and y with x, and then solve for y.

Let's do that:

We get x = 3y + 5

Now, let's solve for y, we get 3y = x - 5

so y = (x-5)/3 which is the inverse.

The inverse of f(x), is symbolized by f^(-1)(x), so we can say

f^(-1)(x) = (x-5)/3

Answer 2

im sorry is 3x+5 over 7

Answer 3

Do the problem identically to the way I just showed you above.

Answer 4

(7x-5)/3
