The domain is all real numbers as a composition of two linear functions have no restrictions (all linear functions have domain of R)
Question 3,4&5 Cindy bought a car for $21,330. A few years later she sold the car for $19,700.find the percent of change in
the value?
1 answer:
The change in value was 8% which amounts to $1630
Further explanation:
The change in value is calculated by using the initial price and selling price of the car.
Given
Purchase Price = P = $21330
Selling Price = S = $19700
As the selling price is less than the purchase price, Cindy had loss.
Percentage of loss will be calculated as:
The change in value was 8% which amounts to $1630

Step-by-step explanation:
The slope within two sets of points is calculated using the slope equation
The slope of a line or points is the rate of change of the line.
This in other words means that, the vertical change per unit horizontal change
Assume that the points are given as:
(x1, y1) and (x2, y2)
The slope (m) of the points is:
Hence, the equation of two sets of points is
