An n th degree polynomial has n real solutions. The graph touches and "bounces off" the x-axis at (-6,0) and (5,0), so x=-6 and x=5 are zeros of even multiplicity. We found the zeroes and multiplicities of this polynomial in the previous section so we'll just write them back down here for reference purposes. One is to evaluate the quadratic formula: Consider the following example to see how that may work. Find the polynomial f(x) of degree 3 with zeros: x = -1, x = 2, x = 4 and f(1) = 8. Check for symmetry. Because the power of the leading term is the highest, that term will grow significantly faster than the other terms as x gets very large or very small, so its behavior will dominate the graph. The next zero occurs at The graph looks almost linear at this point. Polynomial of a third degree polynomial: one x intercepts. The power of the largest term is the degree of the polynomial. The degree will be at least k+1 (if it matches the even/odd we got from step 1), or k+2 (if k+1 doesn't match?). It appears an odd polynomial must have only odd degree terms. If has a zero of even multiplicity, its graph will touch the -axis at that point. This example has a double root. Step 1: Determine the graph's end behavior. The graphs show the maximum number of times the graph of each type of polynomial may cross the x-axis. The basic cubic function (which is also known as the parent cubic function) is f(x) = x 3.Since a cubic function involves an odd degree polynomial, it has at least one real root. It may be represented as \(y = a{x^2} + bx + c.\) 3. The first factor is or equivalently multiply both sides by 5: The second and third factors are and . Note that a first-degree polynomial (linear function) can only have a maximum of one root. To find the degree of a polynomial with one variable, combine the like terms in the expression so you can simplify it. To find the degree of a polynomial with one variable, combine the like terms in the expression so you can simplify it. Simplify within the parentheses first, then apply the .
