Practice problem
made using Desmos
Which of the above piecewise functions are piecewise linear?
Green
Red
Blue
Purple
Type a concept, like “slope” or “photosynthesis”.
![Four piecewise functions:
Green: y=x+3 with domain [-12, -2) and y=3x+7 with domain [-2 , -1].
Blue: y=sqrt(x+5)+4 with domain (-infinity, infinity) and y=x+9 with domain [-10,-5].
Purple: y=3x^2-2 with domain (0,1.5] and y=-x-2 with domain [-2, 0].
Red: y=x-3 with domain [4,10] and y=(x-3)^3 with domain [1,4).](https://d20khd7ddkh5ls.cloudfront.net/desmos-graph-21_2.png)
