Can someone please help me with an Algebra assignment?
Gordon is evaluating some stocks he wants to purchase. You can see the function of the stock price below. The variable x represents days.

anonymous · Answer

This is the table that came with the assignment.

kc_kennylau · Answer

And what's the question?

anonymous · Answer

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.

anonymous · Answer

there are a couple others, I'm just not sure where to start.

anonymous · Answer

No, it says D.

anonymous · Answer

I think so

tylerd · Answer

the lowest starting price is 22

tylerd · Answer

so the second lowest would have to be between 22 and 25

anonymous · Answer

okay, how to i put that into my function. where does it go?

tylerd · Answer

the function is in the form of an exponential function
f(x)=ab^x

so choose a number between 22 and 25, say 23

f(x)=23(b)^x

nincompoop · Answer

you need to know compounding interest

tylerd · Answer

im not sure if they do need to know, looks like regular exponential functions to me.

nincompoop · Answer

whenever the number of days is not indicated, we use the e solution

anonymous · Answer

okay, so what is the e solution then?

nincompoop · Answer

that is something you need to figure out

nincompoop · Answer

read up on compounded and continuous interests

nincompoop · Answer

do you need a textbook or something?

anonymous · Answer

i can google it

tylerd · Answer

did your teacher go over any compound interest?

anonymous · Answer

Technically, it's not my teacher I do school online and i don't remember reading that in the chapter.

tylerd · Answer

ya

tylerd · Answer

i dont think thats what they are asking.

tylerd · Answer

but you should learn it anyway

anonymous · Answer

okay

tylerd · Answer

but for this problem i think something like

$$f(x)=23(1.06)^x$$

would probably work

anonymous · Answer

okay, there are actually two more questions, but for me this subject is kind of confusing. You think you can help?

anonymous · Answer

And thanks so much, I can kinda see how that function would work

anonymous · Answer

I had to read this a couple of times. 
A recent drop in sales has affected Stock D with the function g(x) = –6. Explain to Gordon how Stock D’s new price function, f(x) + g(x), will be created. Graph f(x) + g(x).

kc_kennylau · Answer

Notice that g(x) is a constant.

kc_kennylau · Answer

f(x)+g(x) = 23*1.06^x + (-6)
