This function comes in pieces; hence, the name "piecewise" function. When I evaluate it at various x-values, I have to be careful to plug the argument into the correct piece of the function. They first want me to evaluate at x = –1. Since this is less than 1, then this argument goes into the first piece of the function. To refresh, the ...
