Question

f(x)=xtothefifth and g(x)=-2-3xsqaured which is f(g(x))

Answer 1

(-2-3xsquared)tothefifth

Answer 2

you take g(x) to be your x and therefore insert -2-3x^2 into f(x)

Answer 3

and then you get what @wio just wrote :D

Answer 4

But you still may have to expand it.

Answer 5

when x=t, \[g(t)=-2-3t^2\]
Then \[f(g(t)=(-2-3t^2)^4\]

Answer 6

no, why should you expand it if you already have the simplified version? I mean it depends on what they want but I think it would be pointless to expand to the power of 5 if you already have the expression simplified.

Answer 7

f(g(t))=(−2−3t2)^5, not 4

Answer 8

@Rimplestorck my bad...should be \[f(g(t))=(-2-3t^2)^5\]
