Answer:
(a) 16
(b) 2
(c) 7
Explanation:
Hello!
(A)
Given that -4 is less than 0, we have to square -4 because the Step Function applies that rule to any number less than 0.
The solution for a is 16.
(B)
0 is equal to 0, so the solution is simply 2.
(C)
1 is greater than 0, so we plug in 1 into the equation 3x + 4, as the Step Function applies that rule for numbers greater than 0
- 3x + 4; x = 1
- 3(1) + 4
- 3 + 4 = 7
The solution for c is 7.
