Question

Let f(x) = x + 9 and g(x) = x – 3. What is f(x) • g(x)?

Answer 1

\(f(x) \cdot g(x) = (x + 9)(x - 3)\)

Answer 2

Simplify that

Answer 3

\( \color{Black}{\Rightarrow (x + 9)(x - 3) =x(x-3) + 9(x - 3)}\)

Answer 4

Just multiply (x + 9) by (x - 3).

(x + 9)(x - 3)

x^2 - 3x + 9x - 27

x^2 + 6x - 27

That's your answer. :)

Answer 5

unless you ment
\[f\circ g(x)\neq f(x)\cdot g(x)\]
