Question

14 given $f(x) = -3x + 10$ and $g(x) = x^2 - 7x$ find the following $f(-5) = \boxed{}$ $g(2) = \boxed{}$

Explanation:

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

Substitute \( x = -5 \) into \( f(x) = -3x + 10 \).
\( f(-5) = -3\times(-5) + 10 \)
\( = 15 + 10 \)
\( = 25 \)

Step2: Calculate \( g(2) \)

Substitute \( x = 2 \) into \( g(x) = x^2 - 7x \).
\( g(2) = 2^2 - 7\times2 \)
\( = 4 - 14 \)
\( = -10 \)

Answer:

\( f(-5) = 25 \)
\( g(2) = -10 \)
