Each person who enters a store receives a $5 off coupon. In the equation y = 5x, y is the total value of the couponds given out by 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 ?
The reason being is that the function does not continue in both directions from the origin. Since we cannot have a negative value of people, we cannot use all values of x as inputs in the equation. Therefore, it is not continuous.
The function is not continuous because there can only be a whole number of people. Thus the points would not be connected, and the function is discrete.
