Question

If y = 8x − 2, which of the following sets represents possible inputs and outputs of the function represented as ordered pairs?

{(0, −2), (1, 6), (2, 14)}
{(0, −2), (2, 13), (−5, −40)}
{(1, 7), (2, 7), (3, 7)}
{(1, 6), (2, 13), (3, 24)}

Answer 1

the first set

Explanation:

y = 8x − 2

to see which of the following represent the right input and out put substitute the amount of x in the equation and see it you get the same output .

x y=8x-2 y

0 8(0)-2 -2

1 8(1)-2 6

2 8(2)-2 14
