Question

The function f(x) = –x2 − 2x + 15 is shown on the graph. What are the domain and range of the function?

The domain is all real numbers. The range is y < 16.
The domain is all real numbers. The range is y ≤ 16.
The domain is x. The range is y < 16.
The domain is x. The range is y

Answer 1

Explanation:

The domain is all real numbers. The range is y ≤ 16.

See image below ....

Domain is the set of x values a graph can have ....all real numbers for this graph

Range is the set of y values the graph can have .... a high point of +16 to - infinity for this one....
