1. The domain of the linear regression equation is of: [0,∞).
2. The range of the linear regression equation is of: [0.5,∞).
3. The domain is composed by the input values of the function while the range is composed by the output values.
4. The estimate for the cost of gas in 2025 is of $4.55.
What is the linear regression equation?
The linear regression equation in this problem is defined as follows:
y = 0.176x + 0.5.
In which the variables are given as follows:
- Input x: number of years after 2002.
- Output y: value of gas in year x.
2025 is 23 years after 2002, hence the estimate is given as follows:
y = 0.176(23) + 0.5 = $4.55.
The domain and the range are defined as follows:
- Domain -> set of input values -> years starting at 0 and going until infinite.
- Range -> set of output values -> prices starting at $0.5 and going until infinity.
