one of my problem says that the average slope formula is: $\dfrac{f(x_2)-f(x_1)}{x_2-x_1}$ It tells us the average slope over the interval from $x_1$ to $x_2$ Then it says to take the average slope of the function $x^2+3x+1$ over one unit intervals from $0$ to $10$.

can i use a particular function function to solve this problem?

    You did not give the exact wording of the question, but it sounds like they want $10$ different numbers, $(f(1)-f(0))/(1-0)$, $(f(2)-f(1))/(2-1)$, and so on.2012-08-06

    $f(x)=x^2+3x+1, x_1=0, x_2=10$2012-08-06

    This question was better before it was edited. And it would have been even better if you had quoted the entire exercise like you did [originally](http://math.stackexchange.com/posts/179436/revisions), and _then_ added an explanation of where in it you were stuck.2012-08-06
