Which of the following is a quadratic function?

y = 2x^2 - 12x + 9

Step-by-step explanation:

a quadratic function: y = ax^2 + bx + c

So answer is

y = 2x^2 - 12x + 9

This is y = 2x² - 12x + 9 function.

Step-by-step explanation:

Given :  functions.

To find:Which of the following is a quadratic function.

Solution: We have given functions

Quadratic function :

A quadratic function is one of the form f(x) = ax² + bx + c, where a, b, and c are numbers with a not equal to zero.

We can see from the given options  y = 2x² - 12x + 9  this is in  the  form of quadratic function .

Where a =2 , b= -12 , c= 9.

Therefore , This is y = 2x² - 12x + 9 function.
