Question

Which of the following is a quadratic function?

Answer 1

y = 2x^2 - 12x + 9

Explanation:

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

So answer is

y = 2x^2 - 12x + 9

Answer 2

This is y = 2x² - 12x + 9 function.

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.
