Question

If g(x) = 3x - 5 find g-1(x)

Answer 1

Help Please

Answer 2

To find the inverse, plug in g-1(x) into g(x) and solve for the x.

Answer 3

Err solve for the g^-1(x) rather

Answer 4

so can you show me?

Answer 5

\[g(g^{-1}(x)) =x \]\[\therefore\ g(g^{-1}(x)) = 3(g^{-1}(x)) - 5\]\[\implies x = 3(g^{-1}(x)) - 5\]

Now solve for \(g^{-1}(x)\)

Answer 6

so what is g

Answer 7

is it going to equal x + 5 /3

Answer 8

or one of these
3x + 5

5 - 3x

-3x + 5

Answer 9

Did you solve for it?

Answer 10

Add 5 to both sides,the divide both sides by 3.

Answer 11

so its going to be x+5/3
