Question

question 2 (4 points)
use the following graph to evaluate both $f(-2)$ and $f(4)$
$\circ$ $f(-2) = -2$ and $f(4) = 4$
$\circ$ $f(-2) = -5$ and $f(4) = 1$
$\circ$ $f(-2) = 5$ and $f(4) = -1$
$\circ$ $f(-2) = 0$ and $f(4) = 1$

Explanation:

Step1: Locate $x=-2$ on the graph

Find the point on the line where $x=-2$. The corresponding $y$-value is $5$, so $f(-2)=5$.

Step2: Locate $x=4$ on the graph

Find the point on the line where $x=4$. The corresponding $y$-value is $-1$, so $f(4)=-1$.

Step3: Match with options

Compare the values to the given choices.

Answer:

$\boldsymbol{f(-2) = 5}$ and $\boldsymbol{f(4) = -1}$ (corresponding to the third option: $f(-2) = 5$ and $f(4) = -1$)
