Answer:
The domain is (2,5,-3,0)
Step-by-step explanation:
we know that
For a set of ordered pairs, the first elements of each ordered pair represents the domain of the function and second elements of each ordered pair represents the range of the function.
The domain of a function is the set of all possible values of x
In this problem we have
therefore
The domain is (2,5,-3,0)
Answer:
(A)Decay
(b)0.8
(c)First Term
(d)
(e)$819.20
Step-by-step explanation:
The exponential function for modelling growth or decay is given as:
,
Where:
Plus indicates growth and minus indicates decay.
For a powerful computer that was purchased for $2000, but loses 20% of its value each year.
(a)Since it loses value, it is a decay.
(b)Multiplier
Its value decays by 20%.
Therefore, our multiplier(1-r) =(1-20&)=1-0.2
Multiplier =0.8
(c)$2000 is our First term (or Initial Value )
(d)The function for this problem is therefore:
(e)Since we require the worth of the computer after 4 years,
t=4 years
