To find the inverse of a function, switch the x's and y's, then solve for y again.

y = 2/3x - 17

SWITCH

x = 2/3y - 17

2/3y = x + 17

y = 3(x + 17) / 2

y = x - 10

SWITCH

x = y - 10

y = x + 10

y = cuberoot(2x)

SWITCH

x = cuberoot(2y)

x^3 = 2y

y = x^3 / 2

y = x/5

SWITCH

x = y/5

y = 5x

Hope this helps!
