Inverse Equations Polynomial Question

[Dreyzo]

Hi there, I’m currently doing VCE Maths Methods and I know the general layout for finding inverse equations... swap x &y.... but this question stumped me. Can someone guide me as to how to do it?

f'(x) is the derivative of f(x), not the inverse.
It means differentiate the expression.

What is the FIND of the problem?

What does f'(x) mean (according to your textbook and/or class notes) ?

NOTE the derivative of the function \(\displaystyle f(x)\) is written as \(\displaystyle f ' (x)\) whereas the inverse is written as \(\displaystyle f^{-1}(x)\).

Be careful to read the notation correctly.

As has been noted before, this question is about finding the derivative of a function rather than the function’s inverse. That is calculus. Have you studied calculus? If not, skip this question.
