Which of the following relations represents a function? a {(2, 3), (1, 3), (3, 3)}
c. {(1,3), (2, 3), (1,4)}
b. {(1, 3), (2, 3), (2,4)}
d. {(2, 2), (2, 3), (2, 1)}

A

Step-by-step explanation:

A is the only one that has an x-value that has a unique y-value. C b and d have multiple x-values that have multiple y-values. For example, c has an x-value of 1 which has 2 outputs, which are 3 and 4.

step-by-step explanation:

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
