Actually that's the integral of a to b.

You are integerating from B to A, they give you two numbers in coordinate form. (2(a),3(b)) and you first plug in 3 for the function then plug in 2 for that function and subtract it, so it's actually from B to A.

EDIT Technically you are right, but for the sake of simplicity and avoidance of confusion most teachers and people in general will say integrate from B to A, since it's TOP minus BOTTOM and B is on top.

Welcome to intergral calculus.

Calculus is used mostly to calculate the rate of decay. Everything decays over time.

Personally, I feel that Pre-cal is important. Most college majors only require Algebra2, but I don't see how you can be an successful exec in today's world without Calculus.

..and I think almost everyone (99%) is capable of learning math with enough practice.

Also, parents play a big part in whether their kids will be successful in a hard science. If you've had Cal. or above, then it's very likely that your kids will take at least Cal.

There is no TECHNICALLY- it is the integral from a to b. Any teacher who says it the other way is wrong. Maybe this is indicative of the educational system. Or maybe your teacher does not understand calculus well enough to be teaching it.

Intergral calculus is used to find the area under the curve of two points, thus the diff between points b to a.
