(a)

To determine

The average rate of change of function f in interval [0,1] from the graph and choose the correct options.

The options are:

A) Greater than f(0)

B) Less than f(0)

C) Approximately equal to f(0)

The graph provided is: Explanation

Given information:

The options are:

A) Greater than f(0)

B) Less than f(0)

C) Approximately equal to f(0)

The provided graph is:

When function is increasing or rising the slope of the function is positive and greatest where the curve is more slanted whereas when the function is decreasing or falling its slope is negative and it has the least value where the curve is the steepest.

The derivative at x=0 or f(0) is the slope of tangent at that point

(b)

To determine

The average rate of change of function f in interval [0,2] from the graph and choose the correct options.

The options are:

A) Greater than f(1)

B) Less than f(1)

C) Approximately equal to f(1)

The graph provided is: (c)

To determine

The instantaneous rate of change of function f in interval [2,0] from the graph and choose the correct options.

The options are:

A) Increasing

B) Decreasing

C) Neither increasing nor decreasing

The graph provided is: (d)

To determine

The instantaneous rate of change of function f in interval [2,2] from the graph and choose the correct options.

The options are:

A) Increasing, then decreasing

B) Decreasing, then increasing

C) Approximately constant

The graph provided is: (e)

To determine
