(i) Since the term with highest exponent (power) is 8x 7 and its power is 7. This is quite a bit Give an example of a polynomial P(x) of degree 5 for which x=1 is a critical number but not a local minimum, nor a local maximum. Since the degree of the polynomial is the highest degree of all the terms, it looks like the degree is 2. For example: In a polynomial 6x^4+3x+2, the degree is four, as 4 is the highest degree or highest power of the polynomial. Example: In this unit we will explore polynomials, their terms, coefficients, zeroes, degree, and much more. Read that example carefully. For example, if an input sample is two dimensional and of the form [a, b], the degree-2 polynomial features are [1, a, b, a^2, ab, b^2]. Example: Find the degree of the polynomial 4u4 – 5u3+ 6u2 -8u+3 The degree of a polynomial is the largest exponent on one of its variables (for a single variable), or the largest sum of exponents on variables in a single term (for multiple variables). Note: P(x) ≡ 0 (the zero polynomial) is a polynomial but no degree is assigned to it. 3 Some examples of types of polynomial Polynomial Degree Example Constant 0 from MATH 146-F 146 at City Colleges of Chicago, Wilbur Wright College Example 4.
