Answer:
New price of the stock = $42
Step-by-step explanation:
Given
Price of stock at the start of the day = $35
Increased by 20% by the end of the day.
To find the new price of the stock which is the price of the stock at the end of the day.
Solution:
Price at start =$35
Increase Percent at the end = 20%
Amount of increase in price = ![Increase\ percent \times start\ price = 20\% \times 35 =0.2\times 35=\$7.0](https://tex.z-dn.net/?f=Increase%5C%20percent%20%5Ctimes%20start%5C%20price%20%3D%2020%5C%25%20%5Ctimes%2035%20%3D0.2%5Ctimes%2035%3D%5C%247.0)
∴ New price at the end of the day = ![Start\ price + increase\ in\ price= \$35+\$7=\$42](https://tex.z-dn.net/?f=Start%5C%20price%20%2B%20increase%5C%20in%5C%20price%3D%20%5C%2435%2B%5C%247%3D%5C%2442)
Avg rate of change is given by change in f(x) over change in x, in other words:
![\displaystyle \frac{f(x_2)-f(x_1)}{x_2-x_1}, x_2 > x_1](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cfrac%7Bf%28x_2%29-f%28x_1%29%7D%7Bx_2-x_1%7D%2C%20x_2%20%3E%20x_1)
Substituting the function and your values of x gives:
