If y = 8x - 2, which of the following sets represents possible inputs and outputs of the function, represented as ordered pairs?
{(-1,-1), (3, 15), (4,0)}
O{(7,35), (4, 17), (2, 10)}
{(2,5), (8,50), (9,66)}
O{(-2, -18), (2, 14), (0, -2)}

Answer 1

Answer: {(-2, -18), (2, 14), (0, -2)}

Explanation:

Just took the test

Answer 2

Answer: The right option that represents possible inputs and outputs of the function is the ordered pair

{(-2, -18), (2, 14), (0, -2)}

Explanation:

By crosschecking;

Y=8x-2

When x=-2 , y= 8(-2) -2 , y= -16-2, y=-18 . (-2,-18)

When x=2 , y= 8(2) -2 , y= 16-2, y= 14

(2,14)

When x=0 , y= 8(0) -2 ,y= 0-2, y= -2

(0,-2)
