The question is:

Let f(x)=3 if x is less than or equal to 3 and 6-x if x is greater than 3. Use geometric formulas to finmd the integration from 0 to 5 f(x)dx.

810MemberYou should recognize the two shapes that are enclosed and can find the areas of those pieces.

BTW, what text are you doing that you guys are doing integration at this time of the year?

Add them up to get 14 + 9 = 23.
