Calculus 2 integrals

    1. The problem statement, all variables and given/known data
    Here are the problems

    The problems I need help with are 1 and
    4(a)

    2. Relevant equations
    The second fundamental theorem of calculus

    3. 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.

    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.
