Question

If G(X) = 3x+1, then G-1(1) is

Answer 1

Answer:

0

Step-by-step explanation:

To find the inverse, or $G^{-1}$ , we must switch G(x) and x, and then make G(x) $G^{-1} (x)$ as we are finding the inverse, and G(x) represents the starting equation.

$x = 3G^{-1} (x)+1\\x -1 = 3G^{-1} (x)\\\\\frac{x-1}{3} = G^{-1} (x)$

The steps used here are that we firt subtracted 1 from both sides, and then divided 3 from both sides.

To find $G^{-1} (1)$, we simply plug 1 into x in the inverse function, so our answer is $\frac{1-1}{3} =0$
