The piecewise function tells us specific rules he should execute based on the input x we put in. For example for answer A is true since we use the top function f(x) = -x + 1 since the input is -1 which is less than 0 (x < 0). We check to make sure the equation comes out true:
f(-1) = -(-1) + 1
f(-1) = 2 ✓
Answer is 7
hope it helps
24 1/2 = 24.5
3 1/2 = 3.5
24.5/3.5 = 7
What is the question? Please specific!
