The function h(t) = −5t2 + 15t shown in the graph models the supporting structure of a bridge: graph of parabola starting at zero comma zero, rising from the left to about one and one half comma 11, and falling to the right, ending at 3 comma zero What is the domain of h(t)? All real numbers 0 ≤ x ≤ 11 0 ≤ x ≤ 3 x ≥ 0

not enough information

step-by-step explanation:

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square
