f(x) = x^2- 14x+ 45

Part A: What are the x-intercepts of the graph of f(x)? Show your work factoring and using the Zero Product
Property or share a screenshot from Desmos with the x intercepts.

Part B: Is the vertex of the graph of f(x) going to be a maximum or minimum? What are the coordinates of the
vertex? Again, you may use Desmos.

Part C: Identify the point of the y-intercept for f(x), using Desmos.

Part D: What are the steps you would use to graph f(x)? Justify that you can use the answers obtained in Part
A. Part B, and Part C to draw the graph. Draw the graph or share your screenshot on Desmos.

The price of the new car is 32 998.00 dollars
=> he made a down payment  of 4,200.00 dollars
=> 32 998.00 - 4,200.00 = 28 798 dollars remaining
=> She pays 525 dollars for the next 5 years 
=> 525 * 12 months = 6300 dollars * 5 years = 31 500 dollars
=> 31 500 dollars - 28 798 = 2702
=> 2702 / 5 years = 540.4 dollars is the APR.
