Question

how to find the inverse of my function.
F(X)==5x^2+6

Answer 1

You cannot find "the" inverse of this function. There are two. You must pick one or report both.

Answer 2

how do I pick one?

Answer 3

x = 5y^2 + 6

x - 6 = 5y^2

(x-6)/5 = y^2

\(f^{-1}(x) = \sqrt{\dfrac{x-6}{5}}\;or\;f^{-1}(x) = -\sqrt{\dfrac{x-6}{5}}\)

Generally, find them all (both in this case) and decide what you need.

Answer 4

Solve for \(x\) in term's of \(y\)

Answer 5

ooh thats what you do with the power to the 2nd.. you square it!! that's where i got lost. Thanks!!

Answer 6

Gotta get your algebra up to speed! You WILL get lost.

Good work. Tackle the next one.
