Which of the following are quadratic functions? A. Y=2(x-3x^2+1)  B. Y=5+2x  C. Y=1/2x^2-13x+4  D. Y=x/x-1

anonymous · Answer

a quadratic function contains a polynomial of degree 2 at max..
so A is the answer.

anonymous · Answer

the others can be quadratic?

amistre64 · Answer

you say a max of degree 2, so can a degree 1 be quadratic?

anonymous · Answer

nope.. check by making the all into a linear equation.. the degree of the power of x cannot be more than 2 or less than it as well

anonymous · Answer

Haha ChemGrey, what an awkward way to say that the degree should be to. Have you been watching Monty Python?
The degree shall be no more than 2. Also, the degree shall be no less than 2. 2 shall be the number of the degree and the number of the degree shall be 2.
