Question

Anyone know f(x) and g(x)??

Answer 1

I don't need the answer I just want someone to walk me through it.

Answer 2

Replace every occurrence of "x" in the RHS of f(x), with 5x^2 - 1, and then
simplify.

Answer 3

Okay I understand. Would it be x^2 as well or only x's without exponents?

Answer 4

so would it be 3x^2 - (5x^2 -1) +2 ?

Answer 5

A solution using Mathematica is attached. Mathematica does no leave
algebraic expressions in class room order.

Answer 6

Was the form that I just put correct

Answer 7

The x in the term, 3x^2, also has to be replaced with 5x^2 - 1 .

Answer 8

okay so it's 3(5x^2-1)^2 - (5x^2-1) + 2
