Question

which table represents the function y = 4x - 3? Input x 0 1 2 Output y -3 -2 -1 Input x 0 1 2 Output y -3 1 5 Input x 0 1 2 Output y 1 3 5 Input x 0 1 2 Output y -3 -4 -5

Answer 1

Substitute the valus of x and see which answer fits.
for x=0, y = 4·0 - 3 = -3
for x=1, y = 4·1 -3 = 1

Only the 2nd choice matches:
Input x 0 1 2 Output y -3 1 5
