Its 2,9 because thats the highest it gets which is the maximum

8 0

Answer:

x-intercepts = (8, 0) and (-4, 0)

y- intercept = (0, 8)

vertex = (2, 9)

Step-by-step explanation:

Sorry if its wrong but I think it's where the coordinates are according to the graph. The x-int would hit at the x-axis, y-int would hit the y-axis, and the vertex would be where it's highest point is
