Question

anonymous · Answer

Given that the camera's purchase price is y and the retail price is x.

The function is, y = 0.6x ( why 0.6? Because it is a 40% discount, meaning you pay only 60% of the price).

The domain would be for any positive real value of x. IMportant to note is that the price must be positive.
