Is the relation a function? Why or why not? {(–5, 7), (–2, –1), (0, 3), (4, 7)}

Yes; only one range value exists for each domain value.

No; two domain values exist for range value 7.

Yes; two domain values exist for range value 7.

No; the relation passes the vertical-line test.

Since you can only have 1 output for the inputs, the correct answer would be A- only one range value exists for each domain value.

Step-by-step explanation:

B. Yes; only one range value exists for each domain value.

Step-by-step explanation:

A relation is considered a function only if for each domain value (the values that x-variable takes) only one range value exists (the values that y-variable takes). In this case, the values taken by the x-variable are: -5, -2, 0 and 4; all in different points.

It doesn't matter that two domain values (or more) have the same range value.

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8  

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!
