question
find the value of $f(8)$.
$y = f(x)$
answer

Explanation:

Step1: Locate x=8 on x-axis

Find the position of \( x = 8 \) on the horizontal (x) axis of the graph \( y = f(x) \).

Step2: Find corresponding y-value

From \( x = 8 \), move vertically until intersecting the graph of \( y = f(x) \). The y - coordinate at this intersection point is the value of \( f(8) \). Observing the graph, at \( x = 8 \), the graph reaches its peak (vertex) and the y - value here is 7 (by counting the grid lines or observing the graph's shape, the vertex is at (8,7)).

Answer:

7
