[SPLIT] int[3,7.5]f(x)dx = 10, int[3,4.5]f(x)dx = 5, and

I'm not sure where to start with this one. Can someone give me a nudge in the right way? Thank you.

Use the rule they gave you:

\(\displaystyle \int_a^b\, f(x)\, dx\, +\, \int_b^c\, f(x)\, dx\, =\, \int_a^c\, f(x)\, dx\)

In your case, you'll be subtracting.... :wink:
