Given:
The total cost of renting the warehouse is represented by the equation:
The equation represents the equation of a line
So, both the domain and the range will be corresponding to the possible value of x
The number of persons (x) must be greater than 0, x will not be a negative
So, Domain = (0, ∞ )
and when x = 0, y = 40
So, the range = (40, ∞ )
So, the answer will be
Domain = (0, ∞ )
Range = (40, ∞ )
