That's not the way to show the function for A. But no matter; we have enough information to answer the question.
(i) List the start values.
(ii) Identify the growth rates. We don't have to find a function for B and as it is decreasing we can dismiss it for the question.
(iii) Choose a starting value and growth rate to suit D. It looks like many answers are possible.
edit. I think this is really just a question about functions and graphs. The 'stock rates' is just window dressing.
22<Dstartprice<25, and it's difficult to figure out the growth rate for B, though I can tell that stock fell by 44c, then 43c, may be 42, 42......
Please clarify stock A function.
ps. there are 4 stock functions. The function for D is governed by the statement
It should have the second lowest starting price and the second highest rate of growth. Using complete sentences, justify that your function meets these requirements.
The Price for Stock A is given by the function y= 25(1.08)x, where x is the number of days, 1.08 the rate of growth, and 25 the start price
Gordon is evaluating some stocks he wants to purchase. You can see the function of the stock price below. The variable x represents days.
A: f(x) = 25(1.08)x
B: x f(x)
C: The initial price of this stock is $30, but it has been increasing 4% each day.
1.) Create the price function for Stock D. It should have the second lowest starting price and the second highest rate of growth. Using complete sentences, justify that your function meets these requirements.
2.) Graph the price function for Stock D. Explain the key features of the graph wit
Thank you guys, I thought as much, but you know, when doing it alone you doubt yourself. I have learnt something today : a system with three variables and two equations will NOT yield precise values for the variables, except by inserting the infinite number of all possible solutions. Thanx. Will be back soon.
