Each person who enters a store receives a $5 off coupon. In the equation y = 5x, y is the total value of the coupons given out by the store, and x is the number of people receiving the coupons.
Wen says the function is continuous, because the number of people is unlimited. Is Wen right or wrong? Explain.

Answer:
Wen's wrong!
Step-by-step explanation:
See, the equation y = 5x is a straight line that passes through the origin and extends in both +ve x and -ve x directions. Since, we cannot have the number of people negative in magnitude, hence it doesn't continue in the -ve x direction.
Also, the equation is not valid for decimal points on Cartesian Plane because we can't have the number of people in decimals, we can only have the whole number of people.
