Answer:
The domain is all whole numbers greater than or equal to zero
The range is all real numbers greater than or equal to $27
Step-by-step explanation:
Let
y -----> the income in dollars
x ----> the number of cups of coffee Jim delivers
we have
[tex]y=3x+27[/tex]
The domain is the interval -----> [0,∞)
The domain is all whole numbers greater than or equal to zero (Remember that the number of cups cannot be a negative number or a decimal number)
The range is the interval ------> [27,∞)
[tex]y\geq \$27[/tex]
The range is all real numbers greater than or equal to $27
