Domain: All positive real numbers
Range: Non-negative multiples of 6.50
Step-by-step explanation:
The equation:
f(x) = 6.50x
Since the amount of hour worked cannot be negative.
=> the domain (the differen) values of x, in other the amount of hours worked wcan only be positive = All positive real numbers
Since the f(x) or y depends on x, and x is only positive
=> the range is also going positive and include the multiples of 6.50 (because you are multiplying x by 6.50)
