ok, couple problems:

they give you a graph of velocity [IMG]file:///C:/DOCUME%7E1/student/LOCALS%7E1/Temp/moz-screenshot-1.jpg[/IMG] [IMG]file:///C:/DOCUME%7E1/student/LOCALS%7E1/Temp/moz-screenshot-2.jpg[/IMG]

they ask: what is the average velocity of the plane during the two hour flight? - now, would I just use $\displaystyle \frac{1}{2-0}\int_{0}^{2}{f(x)dx}$

but that would find average distance though, wouldn't it? not velocity

next question:

$\displaystyle f(x) = 3x^3 - 5x^2 + 2x + 2$

Use graph of f(x) to estimate the value(s) of "c" guaranteed by Mean Value Theorem on interval [-1, 2]

Now, I know that $\displaystyle \int_{a}^{b}{f(x)dx = f(c)(b-a)}$

so set up is $\displaystyle \int_{-1}^{2}{f(x)dx = f(c)(3)}$ but then I'm stuck - should I integrate? how do I know what c is supposed to be?

the next question asks: Find the value(s) of "c" analytically.

Um ... help
