Is this a quadratic or linear function? Identify the quadratic,linear, and constant terms

Question

3(x-2)^2+12x

Answer 1

If you have an x^2 term in the function, it is quadratic.

Once you have simplified the function, the numerical value for x^2 is quadratic, the numerical value for x is linear, and other numbers are constants.

(x-2)^2 = x^2 - 4x + 4

3x^2 - 12x + 12 + 12x = 3x^2 + 12

I hope this helps. Thanks for asking.
