    This is incorrect. If the expression is f\!\left(x\right)=3x^2-4x^3+x^4, the largest power is the degree of the polynomial. What do you think is the correct answer?

    2. the function f(x) =-2x(x-1)(x-2)(x+2) has 4 zeros, has a maximum, and has x-> -infinity, f(x)-> -infinity

    This is correct!
