Question

look at this graph:
graph of a parabola opening downward with vertex at (0,0)
what is the y-intercept?

save answer

Explanation:

Step1: Recall y-intercept definition

The y - intercept of a graph is the point where the graph intersects the y - axis. At this point, the x - coordinate is 0.

Step2: Identify the intersection point

Looking at the given graph, the parabola intersects the y - axis at the point (0, 0) because when x = 0, the y - value is 0. So the y - intercept is the y - coordinate of this point.

Answer:

0
