Question

PLEASE HELP. FUNCTIONS AND RELATIONS. The height of a model rocket, h(t), is a function of the time since it was launched, t. What is the domain of h(t)?

Answer 1

Recall that the domain is all the values of the graph from left to right.

From the given graph we get that its domain consists of all values greater than or equal to 0 and less than or equal to 42.

Then the domain of the given function in algebraic notation is:

`0\leq t\leq42.`

Answer: Option D.
