Use the Addition Property for integrals to find values for r and s.

Answer:
Lower limit: -5
Upper limit: -15
Step-by-step explanation:
Notice that the property of addition of integrals shown below, gives the answer to the problem:
[tex]\int\limits^b_a {f(x)} \, dx +\int\limits^c_b {f(x)} \, dx =\int\limits^c_a {f(x)} \, dx[/tex]
therefore, the values you need to type inside the two limits of the integral are:
Lower limit: -5
Upper limit: -15
