Do U Kno How 2 Do this ?

Question

y=5x+1 D=(-1,4,2)

Answer 1

I suspect that D stands for the domain.

From the domain, x = -1, 4, 2

For x = -1,  y = 5(-1) + 1 ----> y = -4

For x = 4, y = 5(4) + 1 ----> y = 21

For x = 2, y = 5(2) + 1 ----> y = 11

Thus for D = (-1,4,2), then R = (-4,21,11), where R is the range.

The ordered pairs are (-1,-4), (4,21), and (2,11).
