Question

Is 3x+y2=5 a quadratic function?

Answer 1

No

Explanation:

To be a quadratic function the variable
`x` would need to be to the second power, like
`x^(2)`.

If the
`y` term is squared it will form a parabola, but since the parabola would be sideways it would not be a function. A sideways parabola would have two outputs for one input.
