Question

The equation of v is shown below.

The graph of w is shown below.

Complete the following sentences to compare the two functions.

Over the interval [2, 6], the average rate of change of v is the average rate of change of w.

The y-intercept of v is the y-intercept of w.

Answer 1

Two concepts here; average rate of change and y-intercept

To find the average rate of change between two generic values (a) and (b)

You will calculate

[f(b) - f(a)] / (b - a)

For v and w

Answer 2

To find the y-intercept, plug in x = 0 or look at the graph to see what the function value is at x = 0
