George plans to purchase a new scooter for $8000 and to keep it until it is worth a fourth of its original price. the value of the scooter is give by v = 8000( 1 8 )t, where v is the value of the scooter and t is the number of years that have passed. if george finds that he can buy the scooter on sale for $6895, how should he change the value equation?

A) Replace the 8000 with 6895

Step-by-step explanation:

The given function is

Where  is the value of the scooter and  is the number of years.

According to the problem, George plans to purchase new scooter for $8000. That means the number 8000 in the given function refers to the price of the scooter. So, if he finds that the scooter costs $6895, then we should replace $8000 with $6895.

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.
