Question

8 given $f(x) = -3x + 10$ and $g(x) = x^2 - 7x$ find the following $g(-3) = \square$

Explanation:

Step1: Substitute \( x = -3 \) into \( g(x) \)

We have \( g(x) = x^2 - 7x \), so substitute \( x = -3 \): \( g(-3)=(-3)^2 - 7\times(-3) \)

Step2: Calculate each term

First, \( (-3)^2 = 9 \), and \( -7\times(-3)=21 \)

Step3: Add the results

Add the two terms: \( 9 + 21 = 30 \)

Answer:

\( 30 \)
