Sketching Polynomial Functions

Let's start by simplifying the given expression using the Distributive Property. Remember, we want our final expression to be in standard form.
Distribute
Note that there is only one variable, Also, the exponents are nonnegative integers, and there are no variables in denominators. Therefore, the expression is a polynomial in one variable. Now, let's identify the leading coefficient and the degree. The leading coefficient is the first coefficient when the polynomial is arranged with descending exponents. Here, the leading coefficient of our polynomial is The degree of a polynomial is the value of the greatest exponent, which in our case is A degree of means that it is a quadratic polynomial.
