Question
Define ƒ : [0, 2] →R by f(x) = 1 for 0 <x <1 and f(x) = 2 for 1< x < 2. Show that f E R(x) on [0, 2] and
compute the integral by following the scratchwork below. Then write a formal proof.
Precisely justify each equality and inequality in the following statement:
3 – e = L(P, f)<
f dx =
f dx =
f dx < U(P, f) = 3.
Now write a formal proof using the steps above. It should have two distinct parts: the part where you
prove that f is integrable, and the part where you prove the value of the integral.
