Question

Find the inverse of f(x)=5x^2. Determine if the inverse is a function.

Answer 1

Let \[y=5x^2\]
\[x=\sqrt{\frac{ y }{ 5 }}\]

This should be the inverse of f(x) and can you tell me if that looks like a function or not?

Answer 2

yes it is a function. i think. the whole def of a function escapes me atm. been working all day. XD

Answer 3

Thats right :)

Answer 4
