    Fundamental Theorm of Calc 1

    Yes, sorry my bad its between -4 and x g(4) would just be the integral of f(x) and using x = 4 as a substitution In this case though, I'm not really sure what f(x) is exactly since it has multiple values or I would just integrate it and sub directly. The Fund Theorm states that if f be a...

    Matrix System of Equations -

    Yeah, I considered that but as you can see in the question s and t act as a constant for the whole column. If I consider s = x, it becomes a problem when I am solving it in terms of x. The question I posted basically has only one possible answer for those blanks or so my prof says. Any ideas?
