Question

(1 point)
Responses

a. A coordinate plane with a parabola, or U-shape graph that opens up. The minimum value of the graph is the point (0, 4.5). The graph does not cross the x axis.

b. A coordinate plane with a parabola, or U-shape graph that opens down. The maximum value of the graph is the point (0, 5). The graph crosses the x axis between 1 and 2 and also between negative 1 and negative 2.

c. A coordinate plane with a parabola, or U-shape graph that opens up. The minimum value of the graph is the point (0, negative 5). The graph crosses the x axis between 1 and 2 and also between negative 1 and negative 2.

d. A coordinate plane with a parabola, or U-shape graph that opens down. The maximum value of the graph is the point (0, negative 5). The graph does not cross the x axis.
