Since the number of buses needed to transport the members on each trip is a function of the number of members who went on each trip, then the independent variable(x) of the function is the number of members who went on each trip and the dependent variable (y) is the number needed. Then each point that represent the function has the form (x,y).

Then, the domain of the function is the set of values that can take the independent variable. In this case, x can take the values $A =\{52,12,86,105\}$ , that is, A is the domain for this situation.

h(t)=-5t^2+10t+3 is the height of a diver above the water, t seconds after the diver leaves the springboard. How high above the

Kobotan [32]

Answer:

3 units

Step-by-step explanation:

So if we want to know how high the spring board is, this will need to be the time at which the diver is still at the top of the board, in this case t = 0 seconds.

So we will need to find h(0)

h(0) = 5(0)² + 10(0) + 3 = 0 + 0 + 3 = 3
