5x           if x < −2

x + 5       if −2 ≤ x ≤ 5

When x=-5,  f(x)=5x, f(−5)  =5*(-5)=-25    

When x=-2, f(x)=x+5, f(−2)  = -2+5=3   

When x=4, f(x)=x+5, f(4)  =4+5=9  

When x=5, f(x)=(x-5)^2,f(5)  = (5-5)^2=0   

When x=8, f(x)=(x-5)^2,f(8)  =(8-5)^2 =9

it saying that it is not 0 for when x=5

Sorry

When x=5, f(x)=x+5,f(5)  = 5+5=10
