Answer:
Step-by-step explanation:
Given: 
, solve for 
To solve for x, we need to isolate it on one side of the equal sign algebraically. In this case, since 
is being multiplied by 
and 
we can divide both sides by and 
to isolate

Answer:
Step-by-step explanation:
The price p, in dollars, of a specific car that is x year old is modeled by the function p(x)=22,255(0.91)^x
a) to determine the cost of a 2 year old car, we will substitute 2 for x in the given function. Therefore
p(2)=22,255(0.91)^2
p(2)=22,255 × 0.8281 = $18673.655
Approximately $18674
b) to determine the cost of a 7 year old car, we will substitute 7 for x in the given function. Therefore
p(7)=22,255(0.91)^7
p(2)=22,255 × 0.51676101936 = 11500.51648579693
Approximately $11501
c) 0.91 indicates exponential decay rate. It is a fixed percentage by which the value of the car decreases every year. It is determined by (1 - rate of decay)
A function is defined as a relation in which each element of a given set (the domain of the function) is associated with an element of another set ( the range of the function).
Note that it is ' an element' in the second set NOT more than one element.
If a graph fails the vertical line test ( the line passes through the graph more than once) it means that there is more than one element in the range associated with the element in the domain - so it is not a function.
