1. Convert each problem into an accumulation function by replacing the upper limit of integration
with a variable. (Don’t use the variable in the integrand.)
For example, Problem 2 is
4 5− x
2 dx 5− x
2 dx −3 You would change it into
u
−3 2. Find an exact formula for your accumulation function. Your answer must be expressed in the
variable you chose in Step 1.
For example, Problem 2 would be
5u − u2 69
