Question

the graph of $y = f(x)$ is shown below. which point could be used to find $f(-4)$? answer $c$ $b$ $d$ $a$ submit answer

Explanation:

Step1: Recall function notation

For a function \( y = f(x) \), \( f(a) \) gives the \( y \)-value when \( x = a \). So to find \( f(-4) \), we need the point where \( x=-4 \).

Step2: Identify the point with \( x = -4 \)

Looking at the graph, point A has an \( x \)-coordinate of -4 (since it's on the vertical line \( x = -4 \)). Points B, C, D have \( x \)-coordinates -5, -3, and 2 (or similar) respectively. So the point with \( x=-4 \) is A.

Answer:

A
