Which function is a quadratic function?

y = -2x² - x is quadratic function.

Step-by-step explanation:

Given : Function .

To find : Which function is a quadratic function.

Solution : We have given that functions .

Quadratic function: A quadratic function is one of the form f(x) = ax² + bx + c, where a, b, and c are numbers.

We can see from given options

y = -2x² - x in form of f(x) = ax² + bx + c,

Where, a = -2 , b = -1 c = 0

Therefore,  y = -2x² - x is quadratic function.
