Question

f(x)=-2x-7, g(x)=-4x3, find f(g(x))

Answer 1

f(g(x)) is another way of saying plug in the equation of g(x) in for x in f(x)

Answer 2

is that 4x^3

Answer 3

wait, what is the g(x) function?

Answer 4

If it is a 4x^3 then it would look like this.
\[f(4x^3)=-2(4x^3)-7\]
Now multiply and simplify
\[f(4x^3)=-8x^3-7\]
