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

Which equation MOST LIKELY matches the graph?

• y = x⁴ - x³ + 3x² + 2

• y = -x⁴ + x³ + 5x + 2

• y = x³ - 2x² + 1x + 3

• y = -x³ - 2x² + 1x + 3

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

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

• x > −3.81 and 0 > x > 3.81

• x < −3.81 and 0 < x < 3.81
  

Remember to look at your roots, multiplicity, and end behavior!! Use your notes!

• y = ^_(x + 2)(x - 1)²

• y = -(x - 2)(x + 1)²

• y = (x - 2)(x + 1)²

• y = -x³
