Which ordered pairs cause this relation NOT to be a function? Why?

{(0, 0.5), (0.5, 1), (3, 1), (1, 6), (3, 2)}

A) (0.5, 1) and (0, 0.5); A function cannot contain decimals.
B) (0.5, 1), (3, 1); The same y-value has different x-values.
C) (3, 1) and (3, 2); The same x-value has different y-values.
D) (3, 1) and (3, 2); The x-value in a function cannot be greater than the y-value.

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3
