1 6.1 Using Properties of Exponents Objectives 1. Use properties of exponents to evaluate and simplify expressions involving powers. 2. Use exponents and scientific notation to solve real life problems. Properties of Exponents Product of Powers Property Power of Power Property Power of a Product Property Negative Exponent Property Zero Exponent Property Quotient of Powers Property Power of a Quotient Property Evaluate. State which property you used.

2 Simplify the algebraic expression. Scientific Notation A number in the form integer. where, 1 c < 10 and n is an An average adult has about 528,000,000 feet of blood vessels in their body. How many times greater is this than the circumference of the Earth, which is about 25,000 miles?

3 6.2 Evaluating and Graphing Polynomial Functions Objectives 1. Evaluate a polynomial function. 2. Graph a polynomial function. Key Terms Polynomial function Leading Coefficient Constant Term Degree Standard Form of a Polynomial Degree Type Standard Form Decide whether the function is a polynomial. If it is, write the function in standard form and state its degree, type and leading coefficient.

4 Evaluate the function using direct substitution, then synthetic substitution. Synthetic Substitution An alternate method for evaluation polynomials. Direct Synthetic Direct Synthetic Direct Synthetic

5 End Behavior of a Polynomial Functions The graph of For > 0 and n even, as as For > 0 and n odd, as as For < 0 and n even, as as For < 0 and n odd, as as Common Graphs

6 Graph the function and describe the end behavior.

7 6.3 Adding, Subtracting, and Multiplying Polynomials 1. Add, subtract, and multiply polynomials. 2. Use polynomial operations in real life problems. Addition and Subtraction of Polynomials Add or subtract the coefficients of like terms (Do NOT change exponents.) Vertically Horizontally Vertically Horizontally

8 Multiply the polynomials both vertically and horizontally. Vertically Horizontally Multiplying Three Polynomials Vertically Horizontally Cube of a Binomial Find the product.

9 6.4 Factoring and Solving Polynomial Equations 1. Factor polynomial expressions. Chapter 5 Factoring General Trinomial 2. Use factoring to solve polynomial equations. Perfect Square Trinomial Difference of Two Squares Common Monomial Factor Special Factoring Patterns Sum of Two Cubes Factor: Factor: Difference of Two Cubes

10 Special Factoring Patterns Factor by Grouping Factor: Factoring into Binomials Factor: Solving Polynomial Equations To solve a polynomial equation 1. Set the equation equal to zero. 2. Factor 3. Set all factors equal to zero and solve. Solve:

11 Solving Polynomial Equations. Find the real number solutions of the equation. Solve: The revenue R in thousands of dollars for a small business can be modeled by Where t is the number of years since In which year did revenue reach \$90,000?

12 6.5 The Remainder and Factor Theorem Objectives 1. Divide polynomials and relate the result to the remainder theorem and factor theorem. Dividing Polynomials Using Long Division Divide: The Remainder Theorem If a polynomial f(x) is divided by x k, then the remainder is r = f(k). Divide Using Synthetic Division Divide:

13 Divide: Divide: The Factor Theorem Factor the polynomial, then find the other zeros of the function. A polynomial f(x) has a factor x k if and only if f(k) = 0. Factor the polynomial given that, then find the other zeros of the function. Factor the polynomial given that, then find the other zeros of the function.

14 6.6 Finding Rational Zeros 1. Find the rational zeroes of polynomial function. 2. Use polynomial equations to solve real life problems. Key Terms Rational Zeros Zeros are Rational Zero Theorem If, has integer coefficients, then every rational zero of the function has the following form: Find the rational zeros of the function.

15 Find the rational zeros of the function. Suppose you have 18 cubic inches of wax to make a candle in the shape of a pyramid with a square base. If you want the height to be 3 inches greater that the length of each side of the base, what should the dimensions of the candle be? Volume of a pyramid: B is the area of the base.
