Answer:
Linear: y=2000 + 25x
Step-by-step explanation:
A linear function, because he will put the same amount in (same rate of change) each month.
y=2000 + 25x
The function which best models the relationship between time and the total amount in the savings account is:
Linear model
The function f(x) which represents the total amount in the savings account in x months is given by:
[tex]f(x)=25x+2000[/tex]
It is given that:
Enrico deposited $2000 in a savings account.
Each month he will deposit additional $25.
This means that the rate at which the amount is increasing each month is constant.
Hence, the model will be linear with a slope 25.
So , if x represents the number of months.
and f(x) represents the corresponding amount in the account.
Then the function f(x) is given by:
[tex]f(x)=25x+2000[/tex]
