7.1 An Introduction to Polynomials Learning Objective: To identify, classify, evaluate, add, and subtract polynomials. Also to describe the shape of the graph. Warm-up (IN)
Exponents are in decreasing order, left to right Learning Objective: To identify, classify, evaluate, add, and subtract polynomials. Also to describe the shape of the graph. Notes Monomial - A number, variable, or the product of a number and one or more variables Polynomial function - Can be written as a monomial or a sum of monomials with whole # exponents Standard form - Exponents are in decreasing order, left to right degree of a polynomial - highest exponent leading coefficient - # in front of highest exponent
Degree Type Standard form # of terms monomial constant binomial 1 Learning Objective: To identify, classify, evaluate, add, and subtract polynomials. Also to describe the shape of the graph. Degree Type Standard form # of terms monomial constant binomial 1 linear trinomial quadratic 2 Polynomial 3 cubic 4 quartic Polynomial 5 quintic Polynomial
