Classify the function as linear or quadratic and identify the quadratic, linear, and constant terms. f (x) = 6x2 + x - 12

F (x) = 6x^2+x-12 is classified under quadratic equations or polynomial equations of degree 2. This is because it takes the general quadratic form of y=ax^2+bx+c.

Where a, b and c are the constants.

Answer: Quadratic
