Q. What is

(f * g)(x)

?

\newline

f(x) = 2x + 6

\newline

g(x) = -3x

\newline

Write your answer as a polynomial or a rational function in simplest form.

\newline

______

Identify formula: Identify the formula for $(f * g)(x)$ . $(f * g)(x)$ is the product of $f(x)$ and $g(x)$ . $(f * g)(x) = f(x) * g(x)$
Given functions: We have: $\newline$ $f(x) = 2x + 6$ $\newline$ $g(x) = -3x$ $\newline$ Which function represents $(f * g)(x)$ ? $\newline$ $(f * g)(x) = f(x) * g(x)$ $\newline$ $(f * g)(x) = (2x + 6) * (-3x)$
Distribute $-3x$ : We found: $\newline$ $(f * g)(x) = (2x + 6) * (-3x)$ $\newline$ Now, distribute $-3x$ to both terms in the parentheses. $\newline$ $(f * g)(x) = 2x * (-3x) + 6 * (-3x)$
Perform multiplication: Perform the multiplication. $\newline$ $(f \cdot g)(x) = -6x^2 - 18x$ $\newline$ Express your answer as a simplified polynomial.
