what is the y - intercept of this quadratic function? (? , )

Answer:

(0, - 4)

Explanation:

Step1: Recall y - intercept definition

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

Step2: Locate on the graph

Looking at the given graph of the quadratic function, when x = 0, the y - value is - 4. So the y - intercept is the point (0, - 4).
