Y=26-4x+2 for x = 0,3,6
find the output, y, for each input, x

x = 0
y = 26 - 4x + 2
y = 26 - 4(0) + 2
y = 26 - 0 + 2
y = 26 + 2
y = 28
(x, y) = (0, 28)

x = 3
y = 26 - 4x + 2
y = 26 - 4(3) + 2
y = 26 - 12 + 2
y = 14 + 2
y = 12
(x, y) = (3, 12)

x = 6
y = 26 - 4x + 2
y = 26 - 4(6) + 2
y = 26 - 24 + 2
y = 2 + 2
y = 4
(x, y) = (6, 4)

Domain (Input): {0, 3, 6}
Range (Output): {28, 12, 4}
{(0, 28), (3, 12), (6, 4)}

Number 40 is a rational number glad i could
