Question

The function h(t) = −5t2 + 20t shown in the graph models the curvature of a satellite dish:

I'll post the ss


What is the domain of h(t)?

x ≥ 0
0 ≤ x ≤ 4
0 ≤ x ≤ 20
All real numbers

Answer 1

@az help c:

Answer 2

The domain is all the possible x-values for your function

So take a look at your graph, where does the x-value start from and then where does it end?

Answer 3

0 and 4?

Answer 4

Exactly, so that would be your domain

x has to be in between 0 and 4

so how would you write that as an inequality?

Answer 5

(it's also the only answer choice with those numbers heh)

Answer 6

hmm it would be B

Answer 7

You got it!

Answer 8

yay tysm

Answer 9

you're welcome :)
