  1. Precalculus Section2.3Graph polynomial functions A polynomial function takes the form: f(x) = axn + bxn-1 + cxn-2 + … dx + e where n is a positive integer. Linear function f(x) = mx + b Quadratic function f(x) = ax2 + bx + c

  2. Cubic function f(x) = ax3 + bx2 + cx + d Quartic function f(x) = ax4 + bx3 + cx2 + dx + e

  3. Graph the following function showing all the intercepts f(x) = x(x+2)(x-1) f(x) = -(x+3)(x+2)(x-1)

  4. Graph the following function showing all the intercepts f(x) = (x+2)2 (x-1) f(x) = (x-3)3

  5. Graph the following function showing all the intercepts f(x) = -(x)3 (x+1) f(x) = x4 – x2

  6. Graph the following function showing all the intercepts
