-1, -35.
When you multiply two negative numbers, you get a positive result.
<h3>
Answer: -2</h3>
========================================================
Explanation:
Plug in x = -1 to find that
f(x) = 2|x-1|
f(-1) = 2|-1-1|
f(-1) = 2|-2|
f(-1) = 2*(2)
f(-1) = 4
If you repeat for x = 1, you should find that f(1) = 0
--------
Now use the average rate of change formula below. Effectively, we're using the slope formula more or less.

The average rate of change on this interval is -2
This is the same as finding the slope through the points (-1, 4) and (1, 0).
Hey there.
We can calculate the total cost by multiplying the price before tax by the decimal form of the sales tax.
This translates to:
619.98 · 0.075 = 46.50 (rounded)
Now we add the listed price and the tax.
619.98 + 46.50 = 666.48
The total cost the bicycle is $666.48
