1)Equation for the first piece , we can find using point-point equation for linear function (y-y1)/(x-x1)=(y-y2)/(x-x2) First point (-3,0) Second point (-1,2) (y-0)/(x+3)=(y-2)/(x+1) y(x+1)=(y-2)(x+3) yx+y=yx-2x+3y-6 3y-y=2x+6 2y=2x+6 y=x+3 f(x)=x+3 is first piece 2) It is a horizontal line, so f(x)=5 is second piece
