Answer 2

Hi!

The correct answer is {56.35, 70.55, 81.2, 116.7} .

Explanation:

The set {17, 21, 24, 34} represents the values of x.

If you replace each value in the equation:

• f(17) = 3.55 * 17 – 4 = 60.35 - 4 = 56.35

• f(21) = 3.55 * 17 – 4 = 74.55 - 4 = 70.55

• f(24) = 3.55 * 17 – 4 = 85.2 - 4 = 81.2

• f(34) = 3.55 * 17 – 4 = 120.7 - 4 = 116.7

Then you have the values {56.35, 70.55, 81.2, 116.7} .
