Question 2: You are comparing the price of two different cars. The cost of car A f(x) after x years can be represented by the function:
Car A: f(x) = 22,500(0.88)x
The table shows the cost of car B g(x) after x years:
Car B:
1 year 24,750
2 years 20,495.48
3 years 16,970.26
g(x), cost in dollars

a) Is the cost of Car A increasing or decreasing? How do you know? By what percentage is it changing each year?

b)What is the percent change for Car B?

c)Whose percent change per year is greater, Car A or Car B?

In which form is the following function written? y = - 2(x – 3)(x + 5)

Is the point (0, 8) on the x-axis or y-axis? how do you know?

When you dilate a figure with a scale factor of 1/2, what will the dilated figure look like?                                                                                           a: the dilated figure will have side lengths that are half the length of the original side lengths.                                                                          b: the angles in the dilated figure will be half the measure of the original figure.                                                                                c: the dilated figure will have side lengths twice the length of the original.
