Hello!

We will have three possible functions, according to the value of x, look:

if x = 0:

f(x) = -2

if x < 0:

f(x) = -x +1

if x > 0:

f(x) = x² -1

Knowing it, let's analyze each statement:

A. f(-1) = 2

f(-1) = -x +1

f(-1) = -(-1) +1

f(-1) = 1+1

f(-1) = 2

TRUE

B. f(-2) = 0

f(-2) = -x +1

f(-2) = -(-2) +1

f(-2) = 2 +1

f(-2) = 3

FALSE

C. f(4) = 7

f(4) = x² +1

f(4) = 4² +1

f(4) = 16 +1

f(4) = 17

FALSE

D. f(1) = 0

f(1) = x² +1

f(1) = 1² +1

f(1) = 1 +1

f(1) = 2

FALSE
