identify whether each if the following represents a quadratic function or not put yes or no
1. y = x² + 2
2. y = 2x - 10
3. y= 9 - 2x²
4. y = 2x + 2
5. y = 3x² + x² + 2

The function is quadratic if the highest degree of any term is 2. Equations 2 and 4 have degree 1, so are linear (not quadratic) functions. Equations 1, 3, and 5 have terms of degree 2 (at most), so are quadratic functions.

_____

We assume that two terms of degree 2 in equation 5 is intentional. If one of those is supposed to be of degree 3 (or more), then that function is not quadratic.
