The degree of a polynomial can be determined by the largest powered monomial of the polynomial.  
What is the degree of the polynomial:
f(x) = -4x³ + 5x - 2

• Degree 2 (quadratic)

• Degree 3 (cubic)

• Degree 4 (quartic)

• Degree 5 (quintic)

The leading coefficient is the coefficient of the largest degree monomial for the polynomial.
What is the leading coefficient for the polynomial f(x) = -4x³ - 2x + 5

• The leading coefficient is -2

• The leading coefficient is 3

• The leading coefficient is -4

• The leading coefficient is 5
