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?
