Question

Is y=x^2 a function?

Answer 1

Yes id it a funtion hope i help can i be brainlites

Answer 2

Yes, it is. Functions can only have one output (y) for each input (x). Furthermore, this means each x value will only have one y passing through it. Thus if we plot it on a graph and it passes through a horizontal line more than once, it is not a function. This is called the vertical line test.
