Verbal Domain&Range

Question

Luis charges a travel fee of $10 plus $25 per month to mow his neighbors' lawns. The equation y = 25x +10 can be used to determine the travel fee for x months. If most of his customers only get their lawns mowed for 5 to 8 months out of the year, what is the range of this situation?

Answer 1

The range is the set of all output (y-) values. So this would be 25x + 10 for x = 5, 6, 7, and 8. So this would be: 135, 160, 185, and 210. Note that this is a discrete function, so under the given constraints, this is a verbal description of the range
