Question

Which of the following statements are true about the graph?

A.The graph has a minimum
B.The graph has a maximum
C.The graph has zeros of -4 and 2
D.The vertex is located at (-1,-9)
E.The graph has y-intercepts at (-4,0) and (0,2)
F.Th solution of the quadratic function represented by the graph is (-1,-9)
G.The y-intercept of the graph is (0,-8)

Answer 1

A, C, D, G

_____
B - the graph is of a quadratic function (apparently). It has a minimum value of -9 as shown on this graph. The maximum is +∞, which is not of interest.

E - the intercepts are (-4, 0) and (2, 0).

F - the vertex is (-1, -9). The solutions are the zeros or x-intercepts (generally), unless the question is asking specifically for the extreme value and where it is located. That is, the solutons to (x +1)^2 -9 = 0 will be -4 and 2.

Answer 2

A,C,D,G

minimum= -9

zeros -4and 2 (aka x-intercept(s))

vertex is (-1,-9)

the y-intercept is (0,-8)
