In which set of points is y a function of x? A) A) {(1, -2), (0, 1), (1, 1), (1, 2)} B) {(1, 2), (0, 1), (1, 2), (-1, 1)}
C) {(2, -1), (0, 1), (1, 0), (2, 1)}
D) {(2, 2), (1, 1), (0, 1), (1, -1)}

answer:  

step-by-step explanation:

odd numbers are only divisible by 1 and itself.

even numbers are divisible by more than 1 and itself.

for example 6 is even because it is divisible by more than 1 and its self. 1 x 6= 6 ; 2 x 3= 6

and 7 is odd because only 7 x 1 equals seveb

step-by-step explanation:

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.
