Diedra has the option to invest in an account that has a declining interest rate. It starts out at 10% but declines to 01% by year 5 If she initially deposits $1500 and never adds any more the account balance can be modeled by f(x) = 1000 + 1000 (graph 1+0.2% shown) She has to decide when to close the account. When would be the best time and why? A) 1 year after she has opened the account because at that time the interest rate is lower than a regulár savings account.
B) 2 years because at that point the interest rate is below 1% so it is not worthwhile.
C)5 years because at that point the amount of money in the account is at the limiting factor so it is not going to grow any more.
D) Would be best if she left it until she needed it so that it could continue to grow at a steady rate.

let's add {f(x)=x+1}f(x)=x+1 and {g(x)=2x}g(x)=2x together to make a new function.

f(x)+g(x) =(x+1)+(2x)=x+1+2x=3x+1

let's call this new function hh. so we have:

{h(x)}={f(x)}+{g(x)}{=3x+1}h(x)=f(x)+g(x)=3x+1

we can also evaluate combined functions for particular inputs. let's evaluate function hh above for x=2x=2. below are two ways of doing this.

method 1: substitute x=2x=2 into the combined function hh.

h(x)

h(2)

​    

=3x+1

=3(2)+1

=7

​ since h(x)=f(x)+g(x)h(x)=f(x)+g(x), we can also find h(2)h(2) by finding f(2) +g(2)f(2)+g(2).

first, let's find f(2)f(2):

f(x)

f(2)

​    

=x+1

=2+1

=3

​  

now, let's find g(2)g(2):

g(x)

g(2)

​    

=2x

=2⋅2

=4

​  

so f(2)+g(2)=3+4=\greend7f(2)+g(2)=3+4=7.

notice that substituting x =2x=2 directly into function hh and finding f(2) + g(2)f(2)+g(2) gave us the same answer!
