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}.

First, you can simplify the function finding the perfect square:

This form of function gives you the coordinates of parabola vertex - (-1,16).

From the diagram you can see that all values for x are possible, then the domain is (all real numbers). Also you can see that values of y decrease from y=16 to , then the range is (or {y|y ≤ 16}).

correct choice is B.

6.9

step-by-step explanation:

simple math really

6 1/2 times 0.6 = 3.9

but if you are just doing 6 and not 6 1/2 then the answer is 3.6

these are pretty self explanatory if you know what supp right and com angles are
