Answer:
D{(0, 0), (-1, -0.5), (-2, -1), (-3, -1.5), (-4, -2)}
Step-by-step explanation:
A function is a relation in which we take every element of the first group and assign an unique element of the second group.
So, the set of ordered pairs that represents y as a function of x is the set that take every value of x and assign an unique value of y.
Then, the set A is not a function because we have the ordered pairs (3,9) and (3,16) in which we have two values of y for the value of x=3.
At the same way, we can said that B and C aren't functions.
Finally, D is the set of ordered pairs that represents y as a function of x because every x has an unique value of y.

Step-by-step explanation:
Histogram is a statistical graph with the use of bar. The bar are not seperated unlike bar chart.
0.320 to 0.329 and 0.360 to 0.369 are of the same frequency which is equal to one. 0.350 to 0.359 is of frequency 2 a little above frequency 1.
Option B and D are very close to each other in value representation. But the frequency of 0.350 to 0.359 in option D is 3. This renders option D invalid and make option B the correct answer.
