You write an equation for each separate graph in this graph. Then you put them all together, but making sure that y=
(-3/2)x+2, x< or equal to 0, y= the square root of 4-x^2, 0<x<2, and y=(x-2)^2, x> or equal to 2.
(-3/2)x+2, x< or equal to 0, y= the square root of 4-x^2, 0<x<2, and y=(x-2)^2, x> or equal to 2.
