√ 2. Quadratic

√ 3. Quadratic

x 4. Not quadratic

x 5. Not quadratic

Explanation:

A quadratic function is of the form

$\large {ax^2 + bx + c}$

where a, b and c are real-valued constants and a ≠ 0

b and c can be 0

The degree of a quadratic function (the highest exponent ) will be 2

#4 has has degree 1

#5 has degree 3

So only 1, 2 and 3 are quadratic functions
