Analyzing Graphs of Polynomials
Graph the function. Identify the x-intercepts.

• x = -5, -2, 2, and 5

• x = -5, 5

• x = -2, 2

• x = -5, -2, 0, 2, 5

Analyzing Graphs of Polynomials
Graph the function. Determine the intervals where the graph is increasing.

• −3.81 < x < 0 and when x > 3.81

• −3.81 > x > 0 and when x < 3.81
  

5.8 - Analyzing Graphs of Polynomials
