What we needed to do with this piecewise function is that we had to find each function once we did that all that we really had to do was just plug it in and the piecewise function is
(-2x+2 if x < or equal to 0 )
y=( The square root of 4-x^2 if 0<x<2 )
( (x-2)^2 if x> or equal to 2 )
(-2x+2 if x < or equal to 0 )
y=( The square root of 4-x^2 if 0<x<2 )
( (x-2)^2 if x> or equal to 2 )
