Carlene sells magazine subscriptions door-to-door. Her earnings in dollars can be found by using the function f(x)=4.5x+12 where
x is the number of subscriptions sold. If she sold at least 9 subscriptions but not more than 13 subscriptions in a day, what is a reasonable domain and range of the function for this situation? Domain: {1, 2, 3, 4, 5} Range: {9, 10, 11, 12, 13} Domain: {1, 2, 3, 4, 5}, , Range: {9, 10, 11, 12, 13}, Domain: {9, 10, 11, 12, 13} Range: {52.5, 57, 61.5, 66, 70.5} Domain: {9, 10, 11, 12, 13}, , Range: {52.5, 57, 61.5, 66, 70.5} Domain: {9, 10, 11, 12, 13} Range: {16.5, 21, 25.5, 30, 34.5} Domain: {9, 10, 11, 12, 13}, , Range: {16.5, 21, 25.5, 30, 34.5}, Domain: {52.5, 57, 61.5, 66, 70.5} Range: {9, 10, 11, 12, 13} Domain: {52.5, 57, 61.5, 66, 70.5}, , Range: {9, 10, 11, 12, 13},
