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

"All real numbers"

Step-by-step explanation:

The domain of a function is the set of x-values that the function is defined for. The set of x-values for which the function has y-values.

Allowed x-values, basically.

Looking at the graph, we would initially think the x values for which there is a function drawn would be from x= 0 to x = 3, but we must remember that this is a continuous function so it stretches upwards and downwards, both. So the set of x-values for which the function is defined is "set of all real numbers".

Normally, a function in the form f(x) = ax^2 + bx, where and b are real numbers, will be a parabola whose domain would be all real numbers.

The function h(t) is in such form, so the domain is "all real numbers".

use formula for the circle a=3.14

i think the correct option is the second option.
