The equation that represents a quadratic function is y = 2x² - 12x + 9
Which of the equations represents a quadratic function?
From the question, we have the following parameters that can be used in our computation:
The equations
By definition
A quadratic function is represented as any of the following forms
y = ax² + bx + c
y = a(x - h)² + k
Using the above as a guide, we have the following:
The equation that is a quadratic function is y = 2x² - 12x + 9
Others are not quadratic functions
