Question

what is the x - value when y = 10 for this function?

Explanation:

Step1: Identify the peak of the parabola

The graph is a parabola opening downward, and the peak (vertex) is at \( y = 10 \). We need to find the \( x \)-coordinate of this vertex.

Step2: Determine the \( x \)-value from the graph

Looking at the grid, the vertex (where \( y = 10 \)) is at \( x = 1 \) (since it's halfway between \( x = 0 \) and \( x = 2 \), or directly at the \( x \)-value corresponding to the peak on the grid).

Answer:

\( 1 \)
