Expert Answer

Step 1

1.

Result used:

Let f be defined on the closed interval [a, b]. The average slope of f between a and b is the quotient

Step 2

Consider the function, f(x)=3x2+5x-10.

Here a=–1 and b=1.

Compute the average slope using the above formula as follows.

Step 3

2.

Result used:

Suppose f(x) is a function which is continuous on the closed interval [a, b] and differentiable on the open interval (a, b).

Then there is a number c such...
