Question:

Determine the leading term, the leading coefficient, and the degree of the polynomial. Then classify the polynomial as constant, linear, quadratic, cubic, or quartic.
a. f (x) = 2x3 + 6x2 - x4 + 11
b. h(x) = -4.7x + 29
c. Find the zeros of the polynomial function and state the multiplicity of each:
f(x) = x(3x - 5) (x - 3)2 (x + 1)3.
