answer
$circ$ $b$ $circ$ $a$
$circ$ $d$ $circ$ $c$
submit answer

Explanation:

Step1: Recall the definition of a function's graph

For a function \( y = f(x) \), the point \((x, y)\) on the graph means \( y = f(x) \). So to find \( f(3) \), we need the point where \( x = 3 \).

Step2: Identify the point with \( x = 3 \)

Looking at the graph, point \( C \) has an \( x \)-coordinate of 3 (since it's at \( x = 3 \) on the x - axis). So this point can be used to find \( f(3) \) because for this point, when \( x = 3 \), the \( y \)-coordinate of the point is \( f(3) \).

Answer:

C. \( C \)
