PLZ HELP LAST QUESTION given the piecewise function given below select all statements that are true f(x)=-x+1,x<0 -2,x=0 x^2-1,x>0 All in brackets A. F(4)=7 Bf(-1)=2 c. F(-2)=0 d. F(1)=0

Step-by-step explanation:

Given the function  f(x)=-x+1,x<0 and f(x) = x^2-1,x>0

when x = 4

f(4) =  -4+1

f(4) =  -3

Also f(4) = 4^2 -1

f(4) = 8-1

f(4) = 7

when x = -1

f(-1) =  -(-1)+1

f(-1) =  2

Also f(-1) = (-1)^2 -1

f(-1) = 1-1

f(-1) = 0

when x = -2

f(-2) =  -(-2)+1

f(-2) =  3

Also f(-2) = (-2)^2 -1

f(-2) = 4-1

f(-2) = 3

when x = 1

f(1) =  -1)+1

f(1) =  -2

Also f(1) = (1)^2 -1

f(1) = 1-1

f(1) = 0

From the calculation above, the correct statements are

A. F(4)=7

B f(-1)=2  

d. F(1)=0

right
