Answer:
No. The input is not feasible ⇒ 3rd answer
Step-by-step explanation:
Lets explain how to solve the problem
- Function is a relation between input and output
- In the function f(x) = y, the input is x and the output is y
- A group of friends ate dinner at the fair last night
- The function g(x) represents the amount of money spent in dollars
where x is the number of friends
- That means x represents the number of people who ate the dinner
and g(x) represents the amount of money they paid
- So x is the input of the function and y is the output of the function
- We need to know does the ordered pair (12.5, $139.50) a possible
solution for g(x)
∵ x represents the number of people
∴ x must be a whole number
∵ The x-coordinate of the solution is 12.5
∵ 12.5 is not a whole number
∴ The x-coordinate of the solution is impossible value
∴ The input is not feasible
∵ y represents the amount of money
∵ The amount of money can be a number with decimal
∵ The y-coordinate of the ordered pair is $139.50
∴ The output could be the amount of money they paid
* The answer is ⇒ <em>No. The input is not feasible</em>
