Which represents a quadratic functionwhich represents a quadratic function? f(x) = 2x3 + 2x2 – 4 f(x) = –7x2 – x + 2 f(x) = –3x + 2 f(x) = 0x2 + 3x – 3

represents a quadratic function.

Step-by-step explanation:

A polynomial of degree two is called quadratic function,

Also, degree of polynomial is the highest power of its monomial ( individual term with non zero coefficient ),

Since, has degree 3,

⇒   is not a quadratic function,

has degree 2,

⇒   is a quadratic function,

has degree 1,

⇒   is not a quadratic function,

has degree 1,

⇒   is not a quadratic function,

this is false ^.^ lol
