A home’s value increases at an average rate of 5.5% each year. The current value is $120,000. What function can be used to find the value of the home after x years? f(x) = 120,000(1.055)x f(x) = 120,000(0.055)x f(x) = 120,000(1.055)x f(x) = [(120,000)(1.055)]x
Answer:
\(f(x)=120,000 \times (1.055)^{x}\).
Step-by-step explanation:
We are given that,
The present value for the home is $120,000 and the rate of interest is 5.5% i.e. 0.055.
As we know that the function for the home is given by,
\(f(x)=P \times (1+r)^{x}\)
where P = present value, r = rate of interest, x = number of years.
So, according to the question, we get that,
\(f(x)=120,000 \times (1+0.055)^{x}\)
i.e. \(f(x)=120,000 \times (1.055)^{x}\).
Hence, we see that the function that represents the value of the home is \(f(x)=120,000 \times (1.055)^{x}\).
The exponential function that is used to find the value of the home after x years is:
\(f(x) = 120000(1.055)^x\)
A increasing exponential function is modeled by:
\(A(t) = A(0)(1 - r)^t\)
In which:
In this problem:
Thus, the function is:
\(f(x) = A(0)(1 + r)^x\)
\(f(x) = 120000(1 + 0.055)^x\)
\(f(x) = 120000(1.055)^x\)
