Answer:
Domain for the given situation is, [tex]0\leq x\leq 50[/tex]
Explanation:
Here, x represents the number of hours
and y represents the daily cost of hiring a plumber.
To repair project can be modeled using the linear function is:
y = 55x + 75
Since, it is also given that the plumber works a maximum of 50 hours per week.
Domain of the linear function is the complete set of possible values of the independent variable(i.e x)
⇒Domain of the given linear function for one week is;
[tex]0\leq x\leq 50[/tex] or
In interval notations [0, 50] where x is the number of hours.
