Question

A computer purchased in 2005 had an initial value of $1800. If the computer depreciates at $200 per year, write a function in x that represents the depreciation in value.

a) f(x)=1800−200x
b) f(x)=200x−1800
c) f(x)=1800+200x
d) f(x)=200x+1800

Answer 1

The function that represents the depreciation in value of the computer over time is f(x) = 1800 - 200x.

Step-by-step explanation:

The answer to this question is option a) f(x) = 1800 - 200x. To represent the depreciation in value of the computer over time, we need to subtract the annual depreciation from the initial value of $1800. Since the depreciation is $200 per year, we can write the function as f(x) = 1800 - 200x, where x represents the number of years.
