Q. What is

(f - g)(x)

?

\newline

f(x) = -2x + 2

\newline

g(x) = -3x^2

\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 difference of $f(x)$ and $g(x)$ . $(f - g)(x) = f(x) - g(x)$
Find Functions: We have: $\newline$ $f(x) = -2x + 2$ $\newline$ $g(x) = -3x^2$ $\newline$ Which function represents $(f - g)(x)$ ? $\newline$ $(f - g)(x) = f(x) - g(x)$ $\newline$ $(f - g)(x) = (-2x + 2) - (-3x^2)$
Combine Terms: We found: $\newline$ $(f - g)(x) = (-2x + 2) - (-3x^2)$ $\newline$ Express your answer as a simplified polynomial or rational function. $\newline$ Distribute the negative sign and combine the like terms. $\newline$ $(f - g)(x) = -2x + 2 + 3x^2$
Rearrange in Order: Rearrange the terms in descending order of the powers of $x$ . $(f - g)(x) = 3x^2 - 2x + 2$
