Question

1. consider the function $f(x) = -6x + 7$.

3a find the value of $f(2)$.
$f(2) = -5$
3b find the value of $f(5)$.
$f(5) = $ enter your next step here

Explanation:

Step1: Substitute x = 5 into f(x)

To find \( f(5) \), we substitute \( x = 5 \) into the function \( f(x) = -6x + 7 \). So we get \( f(5) = -6(5) + 7 \).

Step2: Calculate the multiplication

First, calculate \( -6 \times 5 \), which is \( -30 \). So now the expression becomes \( f(5) = -30 + 7 \).

Step3: Calculate the addition

Then, add \( -30 \) and \( 7 \). \( -30 + 7 = -23 \).

Answer:

\( f(5) = -23 \)
