The second fundamental theorem of calculus

The Attempt at a Solution


For problem 1, I calculated the areas under the curve (using remmien summs) and tried to find the x value that would approximate f(x)=-.75

For problem 4(a), all i did was that since it was an integral, taking the derivative would just be the integrals and that's how I got that answer.[/B]

I mean integrand

For 4(a), the problem with yours is that they are asking for f(2)=3, that is, when x=2 f(x)=3. What you've done is set your interval from x to 2. That means the interval for f(2) is from 2 to 2. Which will always be 0.

I can't tell what is going on for 1. You'll need to explain the question better.
