A group of friends go to the movies. The function h(x) represents the amount of money spent, where x is the number of friends at the movies. Does a possible solution of (6.5,$95.25) make sense for this function?
A) Yes. The input and output are both peoples
B) No.The input is not possible
C) No.The output is not possible
D) No. neither the input nor output is possible

Since the solution given is a coordinate point on a graph, there is an x and y coordinate. In this scenario, the x coordinate is given as the number of friends, and y (aka h(x)) is given as the total amount of money spent.

When we look at the values give, we do not need to mathematically evaluate anything, as it is simply asking us whether or not the values are plausible. The amount of money is plausible, as it accounts the dollars and cents, but the amount of people is not, because we cannot have half of a person as a solution point. Therefore, the input, or x, is not possible.

(Note that typically, the x coordinate is an input, and the y coordinate is an output, as y values usually depend on the x value)
