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

0 | 3 8

1  | 2 2 4

2 | 0 1 3 6

3 | 4

Step-by-step explanation:

The first row is for numbers 0-9, the second row is for numbers 10-19, the third row is for numbers 20-29, and the fourth row is for numbers 30-39. The first column indicates the tens and the second column indicates the ones. Notice that 12 appears twice in the list and in the stem and leaf diagram. This diagram allows us to easily see the distribution of the data.
