Given that:
The tables values which represents Age and Admission Price is
Age Admission Price
under 5 free
5–17 $25
18–64 $40
65 and over $35
To find:
Domain and range of the function.
Solution:
Domain is the set of input values.
Here, domain is age because age is an independent variable.
Age cannot be negative, so
[tex]Domain:\{Age\geq 0\}=[0,\infity)[/tex]
Therefore, the domain is all number greater than or equal to 0.
Range is the set of input values.
Here, range is Admission Price because Admission Price is a dependent variable.
Admission Prices are free (i.e., 0), $25, $40 and $35. So
[tex]Range:\{0,25,35,40\}[/tex]
Therefore, range is {0,25,35,40}.
