Question

Find inverse of f(x)=3x+1

Answer 1

First, replace f(x) with y.

So we have now:

y = 3x + 1

Next, switch the x and y.

We get:

x = 3y + 1

Finally, solve for y.

3y = x - 1

y = x/3 - 1/3

So, we have f(x) = 3x + 1, and the inverse of this function is:


`\boxed{f^(-1)(x) = (1)/(3) x - (1)/(3)}\\\\OR\\\\\boxed{f^(-1)(x) = (x-1)/(3)}`
