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

this answer is !

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
