Answer:

1. Quadratic

2. Not quadratic

3. Not quadratic

4. Quadratic

Explanation:

A quadratic equation will have a degree of 2. The degree is the highest power of the x term in the equation.

Therefore a quadratic equation will be of the form

y = ax² + bx + c,

where a, b and c are constants

a ≠ 0 but either b or c or both can be 0
