(a) Output = 37

(b) Input = 9

Step-by-step explanation:

Given

y =x5 - 3

Solving (a): Output, when input = 8

This means that, we solve for y when x = 8

So, we have:

y =x5 - 3

y =8*5 - 3

y =40 - 3

y = 37

Solving (b): Input, when output = 42

This means that, we solve for x when y = 42

So, we have:

y =x5 - 3

42 = x5 - 3

Collect like terms

x5 = 42 + 3

x5 = 45

Divide both sides by 5

x = 9
