Question

4 given $f(x) = -x + 6$ and $g(x) = x - 2x$ find the following

$f(-5) = \square$

$g(4) = \square$

Explanation:

Step1: Find \( f(-5) \)

Substitute \( x = -5 \) into \( f(x) = -x + 6 \).
\( f(-5) = -(-5) + 6 \)
\( = 5 + 6 \)
\( = 11 \)

Step2: Find \( g(4) \)

First, simplify \( g(x) = x - 2x = -x \). Then substitute \( x = 4 \) into \( g(x) = -x \).
\( g(4) = -4 \)

Answer:

\( f(-5) = 11 \)
\( g(4) = -4 \)
