Answer:
The range of the function is
Step-by-step explanation:
Consider the provided information.
The plumber charges a fixed cost of $80 plus an additional cost of $45 per hour.
Let plumber works for x hours, then the required linear function will be:
The plumber works a maximum of 8 hours per day.
That means the minimum value of x is 0 and maximum value of x is 8.
We need to find the range of the function.
Range of the function is the set of y values.
Substitute x=0 in above function,
Now substitute x=8 in above function.
Hence, the range of the function is
