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

Explanation:

Step1: Understand the problem

We need to find the value of \( f(-3) \) from the graph of \( y = f(x) \). This means we look for the \( y \)-coordinate of the point on the graph where \( x = -3 \).

Step2: Locate \( x = -3 \) on the x - axis

On the given graph, find the vertical line corresponding to \( x=-3 \). Then, find the point where this vertical line intersects the graph of \( y = f(x) \).

Step3: Determine the y - coordinate

By looking at the graph, when \( x=-3 \), we can see that the point on the graph has a \( y \)-coordinate of \( 4 \) (by observing the grid and the position of the curve at \( x = - 3 \)).

Answer:

\( 4 \)
