Using the domain and the range of the function, it is found that the correct option is given by:
4- Both f(x) and g(x) include domain values of [12, ∞), and both functions increase over the interval (12, ∞).
What are the domain and the range of a function?
- The domain of a function is the set that contains all the values of the input.
- The range of a function is the set that contains all the values of the output.
Function f(x) is defined by: f(x) = 12x.
- Line with positive slope, hence it is increasing all over it's domain.
- Range is all real values.
- No restriction, hence the domain is also all real values.
Function g(x) is defined by: [tex]g(x) = \sqrt{x - 12}[/tex]
- The square root function increases over all it's domain.
- The range is [tex](0, \infty)[/tex].
- The term inside the root cannot be negative, hence the domain is [12, ∞), which is contained into the domain of f(x).
This means that option 4 is correct.
