The function is a parabola which opens downwards.
-x^2 - 2x + 15
-(x^2 + 2x) + 15
= -[(x + 1)^2 - 1 ]+ 15
= -(x + 1)^2 + 16
The domain is all real numbers and the range is {y|y <= 16}
Its the second choice.
When constructing the histogram, the intervals are selected in such a way that the width of each interval is the same and the gap between two intervals stays uniform throughout the histogram. This makes the data easy to visualize, easy to interpret and easy to understand.
From the given options, option B lists the intervals in an absurd order. First interval is from 0 to 3. There is no gap between first and second interval and the second interval is larger than the first. So these intervals cannot be the set of intervals of a histogram.
So, the answer to this question is option B

Answer:
Marcy's math class starts at 9:35.
Step-by-step explanation:
11:55
-50 = 11:05 This gets rid of 50 minutes of math class.
11:05
-30 = 10:35 This gets rid of the 30 minutes of recess.
Now subtract one more hour to subtract the remainder of math class, and you get 9:35. Marcy's math class starts at 9:35.
