| To find the values of the function given by the formula y = 4x – 8 for a given value of the argument, you need to substitute this value in this function formula instead of x and calculate y.
1) For x = -3:
y = 4 * (-3) – 8 = -12 – 8 = -20.
2) For x = 0:
y = 4 * 0 – 8 = 0 – 8 = – 8.
3) For x = 1:
y = 4 * 1 – 8 = 4 – 8 = – 4.
4) For x = 6:
y = 4 * 6 – 8 = 24 – 8 = 16.
Answer: 1) y = -20; 2) y = -8; 3) y = -4; 4) y = 16.
