Answer:

Find the amount for $250 compounded yearly at a rate of 25% for a period of x years.

Step-by-step explanation:

Given the function f(x) defined as follows:


f\mleft(x\mright)=250\mleft(1.25\mright)^x

We can rewrite f(x) as:


f\mleft(x\mright)=250\mleft(1+0.25\mright)^x

If we compare this with the compound interest formula:


A=P(1+r)^x

We can see that:

• Principal, P=250

,

• Interest Rate =0.25 = 25%

A word problem for the function will be:

Find the amount for $250 compounded yearly at a rate of 25% for a period of x years.
