Answer 1

did you pick one or do you need help with this?

Answer 2

Haven't picked one yet

Answer 3

remember \[f\circ g(x)=f(g(x))\] and work from the inside out
so the first step is \[f(g(x))=f(x^2)\]

Answer 4

second step is to replace the \(x\) in \[f(x)=4x-1\] with \(x^2\)

Answer 5

that will give you \(f(x^2)\)
if you are still confused, let me know

Answer 6

I'm kinda getting it but I'm not sure which would be the answer

Answer 7

\[f(g(x))=f(x^2)=4x^2-1\] you gotta replace \(x\) by \(x^2\) here

Answer 8

Ohhh I see.
