Answer:
Part A: missing boxes, from left to right, 5, -3, 0
Part B: graph B.
Explanation:
Part A: You can use the graph to answer this question OR plug in the given X and solve for Y.
x = -1, y = 5
(-1^)2 - 4(-1) = 1+4 = 5
x= 1, y = -3
1^2 -4(1) = 1-4 = -3
x = 4, y = 0
4^2 - 4(4) = 16-16 = 0
Part B: Choose graph B. It goes through the origin (no intercept). It matches the points above,
