Question

What is the domain of h

Answer 1

The domain is the real numbers in a (closed) interval [-4,8]

Explanation:

This is a continuous function with a domain of real numbers between (and including) -4 and 8. This is written as an interval [-4,8], or as
`-4\leq t\leq 8`

Answer 2

D : { -4 ≤t ≤8}

Explanation:

The domain is the input values or what t can equal.

From the graph, t is equal to -4 all the way to and including 8

D : { -4 ≤t ≤8}
