find the value of f(-3).
y = f(x)
(graph of a parabola y = f(x) with x-axis from -10 to 10 and y-axis from -10 to 10)
answer attempt 1 out of 2

Explanation:

Step1: Locate x = -3 on the x - axis

Find the position of \( x=-3 \) on the horizontal (x) axis of the graph.

Step2: Find the corresponding y - value

From \( x = - 3\), move vertically until intersecting the graph of \( y = f(x) \). The y - coordinate at this intersection point is the value of \( f(-3) \). By observing the graph, when \( x=-3 \), the corresponding \( y \) - value (which is \( f(-3) \)) is - 9.

Answer:

\( f(-3)=-9 \)
