Question

14 given f(x) = -x + 6 and g(x) = x - 2x find the following f(-5) = g(4) =

Explanation:

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

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

Step2: Simplify \( g(x) \) first

Simplify \( g(x) = x - 2x \) to \( g(x) = -x \).

Step3: Calculate \( g(4) \)

Substitute \( x = 4 \) into \( g(x) = -x \).
\( g(4) = -4 \)

Answer:

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