    \(\int_a^bcx^ldx = \frac{c}{l+1}x^{l+1}|_a^b\)

    where \(f(x) |_a^b \implies f(b) - f(a)\)

    I'm suppose to interpret it but I am not understanding what he means(my professor). He says I think to explain it not solve it

    graph the function you are taking the integral of. i.e. graph \(f(x) = 200x^{1.075}\)

    a function of which a given function is the derivative, i.e., which yields that function when differentiated, and which may express the area under the curve of a graph of the function.

    Graph the function. then it is the area between 5 and 10

    not just under the curve.... I think that is a bad way of saying it... we must balance out the negative when looking at it as area...

    an integral is basically the area under a curve

    so it's basically plotting population between the years of 5 and 10 and what the growth potential is
