The equation yˆ=1.21x2−15.98x+156.28 approximates the average cost, in thousands of dollars, of a home in a particular county, x years after the data collection began. What is the best estimate for the average cost of a home 4 years after the data collection began? rounded to the nearest tenth, in the box.

correct choice is a

step-by-step explanation:

the equation of the line passing through the points and is

thus, the equation of the line that passes through the points (0, -6) and (-3, 0) is

change of stock price/initial stock price on friday * total stock value = change of stock value

0.89/73.73 *x = 42.72

x=3539.04 = total stock value at initial stock price on friday .

total stock value at initial stock price on friday/ initial stock price on friday = number of shares

3539.04/73.73 = 48 shares

they own 48 shares of this stock
