7.1 Polynomial Functions Objective: Evaluate Polynomials Identify general shapes of graphs of polynomials
Polynomial Function(in one variable) • degree of f(x): highest exponent • leading coefficient: the coefficient of the term with the highest degree
Examples: • State the degree & leading coefficient
Evaluate a Polynomial Function • Find f(6) • Find g(3)
Find f(a2) • Find f(h+3)
Graphs of Polynomial Functions • Constant Function degree = 0 =4 • Linear Function degree = 1
Graphs of Polynomial Functions • Quadratic Function degree = 2 =4 • Cubic Function degree = 3
Graphs of Polynomial Functions • Quartic Function degree = 4 • Quintic Function degree = 5
End Behavior of EVEN DEGREE • Leading Coefficient Positive • Leading Coefficient Negative
End Behavior of ODD DEGREE • Leading Coefficient Positive • Leading Coefficient Negative
Zeros (or Roots) The number of REAL ZEROS a polynomial can be determined by how many times the graph crosses the x-axis.
For each graph, - End Behavior?- Even or Odd?- # of Real Zeros? Even 1 Real Zeros Odd 3 Real Zeros Odd 3 Real Zeros
