Using straight-line depreciation, the value V of a particular computer x years after purchase is given by the linear function V(x) = 1,800 - 360x for 0 ≤ x ≤ 5.

AWhat are the independent and dependent variables?
BWhat is the domain of this linear function?
CWhat is the initial value of the computer?
DWhat is the value of the computer 2 years after purchase?
EGraph the linear function over its domain.

(f) After how long will the value of the computer be $0?

Verified Answer :

Avalue is dependent and time is independent
b) domain is x between 0 and 5 inclusive
c) the value at x = 0 or 1800
d) 1800 - 360 (2) = 1080 is the value after 2 years
e) graph the points (0, 1800); (2, 1080) and draw a line between them
f) 360x = 1800
× = 5
it will be 0 after 5 years
