question
find the value of f(4).
y = f(x)
answer attempt 2 out of 2

Explanation:

Step1: Locate x=4 on x - axis

Find the vertical line at \( x = 4 \) on the coordinate plane.

Step2: Find intersection with graph

The graph of \( y = f(x) \) intersects the vertical line \( x = 4 \). From the graph, at \( x = 4 \), the y - coordinate (which is \( f(4) \)) is 5 (by visually checking the grid, the peak of the parabola - like graph is at \( x = 4 \) with \( y = 5 \)).

Answer:

5
