For a certain function fff you are told two values:
∫15f(x) dx=12∫19f(x) dx=7\int_{1}^{5} f(x)\,dx = 12 \qquad\qquad \int_{1}^{9} f(x)\,dx = 7∫15f(x)dx=12∫19f(x)dx=7
What is ∫95f(x) dx\displaystyle\int_{9}^{5} f(x)\,dx∫95f(x)dx?
Look carefully at the order of the limits on the integral you are being asked for.
Select all that apply.
