Scene 2

A  polynomial function  is a  function  that involves only non-negative integer powers or only positive integer exponents of a variable in an equation like the quadratic equation, cubic equation, etc.

Scene 3

EXAMPLE: IDENTIFYING ZEROS AND THEIR MULTIPLICITIES

The polynomial function is of degree  n   which  is 6. The sum of the multiplicities must be 6. Starting from the left, the first zero occurs at x=−3x=−3. The graph touches the  x -axis, so the multiplicity of the zero must be even. The zero of –3 has multiplicity 2. The next zero occurs at x=−1x=−1. The graph looks almost linear at this point. This is a single zero of multiplicity 1 . The  last zero occurs at x=4x=4. The graph crosses the  x -axis, so the multiplicity of the zero must be odd. We know that the multiplicity is 3 and that the sum of the multiplicities must be 6.

3,a<0
This equation is a linear function with a negative
lead coefficient (goes from Q2 -Y Q4 and has a y-
intercept of -3. It matches with graph vi.
k(x) —ax 2 bx 2,a 0
This equation is a quadratic function with a
negative lead coefficient (goes from Q3 Q4
and has a y-intercept of -2. It matches with
graph iii.
q(x) ax 3, a 0
This equation is a linear function with a positive
lead coefficient (goes from Q3 QI and has a
y-intercept of -3, It matches with graph ii.
