To determine

## Determine whether the equation defines y as a function x or not.

Expert Solution

The last equation is a rule that gives one value of y for each value of x ,

So, it defines y as a function of x .

### Explanation of Solution

Given information: consider the equation x+y2=14

Calculation:

Now solve y in terms of x gives,

y2=14xy=±14x

The last equation is a rule that gives one value of y for each value of x ,

So it defines y as a function of x .

Thus, write the function as y=±14x
