Question

Find f(g(x)) if f(x) = x - 4 and g(x) = x2.

Answer 1

\( \color{Black}{\Rightarrow f(g(x)) = f(x^2) = x^2 - 4}\)

Answer 2

Factor that thing^

Answer 3

\( \color{Black}{\Rightarrow x^2 - 2^2 = (x + 2)(x - 2) \text{ using difference of squares.}}\)

Answer 4

is it x^2-4, x-4, x^2-2, or x^2+8x+16?

Answer 5

As I said, \(x^2 - 4\)
