Question

d) identify the y-intercept. enter your answer as an ordered pair.
e) graph the quadratic equation by plotting the vertex and one other point.
shift + scroll to zoom.
shift + drag to pan.

Explanation:

Step1: Recall y-intercept definition

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

Step2: Identify the point on the graph

Looking at the given graph of the quadratic function, the point where the graph intersects the y - axis (x = 0) has a y - coordinate of 0 (from the vertex at (0,0) which is on the y - axis). So the ordered pair for the y - intercept is (0,0).

Answer:

(0, 0)
