  1. Sketch the graph of the polynomial function.
    i)
    P(x)=x−2P\left( x \right) = x - 2
    ii)
    P(x)=(x−2)2P\left( x \right) = {\left( {x - 2} \right)^2}
    iii)
    P(x)=(x−2)3P\left( x \right) = {\left( {x - 2} \right)^3}
    iv)
    P(x)=(x−2)4P\left( x \right) = {\left( {x - 2} \right)^4}
    v)
    P(x)=(x−2)5P\left( x \right) = {\left( {x - 2} \right)^5}
  2. Given that the graph shows a degree-eight polynomial and the zero x=3x = 3 has a multiplicity of 2, determine the multiplicity of the zero x=−2x = - 2.

  3. Without using a graphing calculator, make a rough sketch of the following polynomial: P(x)=−112907776(x+3)(x+1)2(x−2)3(x−4)4(x−7)5P\left( x \right) = - \frac{1}{{12907776}}\left( {x + 3} \right){\left( {x + 1} \right)^2}{\left( {x - 2} \right)^3}{\left( {x - 4} \right)^4}{\left( {x - 7} \right)^5}
