Question

Does the equation x^2+y=144 define y as a function of x?

Answer 1

The given equation is

`x^2 + y = 144`

First we solve for y, and for that, we have to islolate y, that is

`y= 144-x^2`

And it pass the vertical line test. So here y is a function of x .

So we can define the given equation as y as a function of x .
