Can someone please help me understand this

No, because one x-value corresponds to two different y-values.

Step-by-step explanation:

Given a function where x represents an input of a particular value, which gives an output for that particular value inputted as defined by the function, if the function is true and valid, a particular value of input should not give us different values of output.

Thus, from the table given, at x = 5, we have y = 3.

Also, at x = 5, we have y = 2.

Here, one x-value is given us two different y-values. This is not true if a function. We cannot regard the table given as representing a function.

Therefore, the answer is:

No, because one x-value corresponds to two different y-values.

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.

the factors of 15 are 1, 3, 5, and 15.

hope that , fam!
