Fundamental Theorem of Algebra:
**Remember, a root is the same as a zero or an x-intercept. Roots can be real or imaginary!!!
**The degree of a polynomial is determined by its highest degree exponent when a function is written in standard form (i.e. fx= ax2+bx+c). If a function is not written in standard form (i.e. fx=(x−r1)(x−r2)(x−r3)), the x’s must be multiplied together to find the highest degree first.
**The y-intercept of a polynomial function will be the “c” value or the number that does NOT have an x attached to it.

Number of Extrema can easily be found if you identify the degree of the function. The number of extrema is always AT MOST one less than the degree of the function.
Determine the degree and POSSIBLE number of extrema for each of the following:
