Question: Piecewise Function Question

I tried using the piecewise function and only got it to work by using the boolean operator and.

The two conditions were:

1: 0<= x <=a

2: a<= x <=b

However, just using the two conditions as they're written above with the function piecewise gave me error statements.

Is the only way to use such conditions in the piecewise function, is by using the conjunctive ? (i.e. writing it as 0<=x and x<=a, f1, a<=x and x<=b, f2).
