Question

the graph of $y = f(x)$ is shown below. according to the graph, what is $f(4)$?
answer
$\circ$ $-2$ $\circ$ $4$
$\circ$ $1$ $\circ$ $-3$

Explanation:

Step1: Understand the function notation

To find \( f(4) \), we need to determine the \( y \)-value of the function \( y = f(x) \) when \( x = 4 \). This corresponds to the point on the graph where the \( x \)-coordinate is 4.

Step2: Locate the point with \( x = 4 \)

Looking at the graph, the point labeled A has an \( x \)-coordinate of 4. We check the \( y \)-coordinate of this point. From the graph, the \( y \)-coordinate of the point with \( x = 4 \) is 1.
