Question

Given the piecewise function shown below, select all of the statements that

are true.
F(x)= [-x+1, x <0]
[-2,x=0]
[x ² – 1, x > 0]

A) f(4) = 7
B) f(1) = 0
C) f(-1)=2
D) f(- 2) = 0

Answer 1

9514 1404 393

Answer:

B, C

Explanation:

The attached shows the function values for x={4, 1, -1, -2} are {15, 0, 2, 3}.

Statements ...

• f(1) = 0
• f(-1) = 2

are correct.
