During the economic downturn in 2008, the price of a stock, A(x), over an 18-month period decreased and then increased according to the equation A(x) = 0.70x^2 - 6x + 15, where x equals the number of months. The price of another stock, B(x), increased according to the equation B(x) = 2.75x + 1.50 over the same 18-month period. State all
prices, to the nearest dollar, when both stock values were the same.

The first time both stock prices were the same they cost approximatley $ 1.803 .00.

The second
time both stock prices were the same they cost approximatley $ 30.917.00.

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
