Answer:
Third one
Step-by-step explanation:
To be a function x must only have 1 y value or you're really describing a limit which isn't part of the outputs
However, In your case two x values equaling the same y value is fine because the x values do not have two y values
This is a function, as each x value corresponds to one y value
My apologies I was confused with my first answer.
Simply set up a proportion. 1/3 = x/48. Cross multiply afterwards. 48 = 3x. Solve the equation. x = 16. By using proportions which is another form of a ratio you can easily find out that there are 16 adults at the school. Hope this helps :))
