Please Help me with this exam question.
mel-nik [20]

Based on the function given, the domain of f(x) is -18 ≤ x ≤ 10 and the range is 16 ≤ f(x)  ≤ 95

<h3>What are the domain and range?</h3>

The domain of a function is found by looking at a graph from left to right. This means that x will be equal to or greater than the smallest x value and less than or equal to the largest x value.

Domain is therefore:

-18 ≤ x ≤ 10

The range can be found by looking at the y value. The value if f(x) will be equal to or greater than the smallest y value and less than or equal to the largest y value.

Range is:

16 ≤ f(x)  ≤ 95
