Question

inverse of the equation f(x)=1/3x+2
i think its g^-1(x)=3x-6?
please help

Answer 1

looks good

Answer 2

g^-1(x)=3x-6 that is correct?

Answer 3

I just wanted to a make sure because when I graphed it, it didnt look like it would be opposite

Answer 4

???

Answer 5

What makes you think it's that?

Answer 6

kathline?

Answer 7

Yes, you're correct. That's what I got.

Answer 8

notice how any 2 points on the line are "reversed" between the line and its inverse. the easiest 2 to look at are the x and y intercepts

Answer 9

because you first replace fx with y so y=1/3x-2, then solve for x interms of y so 1/3x=y-2 and get x=3y-6 then swap postions of variable y=3x-6 and then replace y with g(x) so therfore g^-1(x)=3x-6?

awesome thank you so much!!
