Question

the graph of a function f is shown below. find f(0).

Explanation:

Step1: Understand \( f(0) \) meaning

\( f(0) \) is the \( y \)-value when \( x = 0 \) (the \( y \)-intercept).

Step2: Locate \( x = 0 \) on graph

Find the point where \( x = 0 \) (the \( y \)-axis) intersects the function's graph. The vertex is at \( (0, -1) \), so when \( x = 0 \), \( y = -1 \).

Answer:

\( -1 \)
