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|y < 16}.
The domain is all real numbers. The range is {y|y ≤ 16}.
The domain is {x|–5 < x < 3}. The range is {y|y < 16}.
The domain is {x|–5 ≤ x ≤ 3}. The range is {y|y ≤ 16}.

Answer 1

ok i read it 3 times
aren't there really only two answer choices there?

Answer 2

oh i see the difference, sorry

Answer 3

in any case if you have a quadratic, the range would be all real numbers unless otherwise restricted

Answer 4

i got the answer. thank you tho

Answer 5

ok good
