 0 8 -8 4
•  Question 3: 1 pts evaluate $x^{17}+4x^{12}-5x^2-x+1$ for $x = 0$
 1 11 111 1111
•  Question 4: 2 pts evaluate $x^{53}+x^{28}+1$ at $x =-1$
 -1 0 1 2
•  Question 5: 2 pts It is easier to evaluate a polynomial before like terms have been combined than after.
•  Question 6: 2 pts if $p(x) = x^2+x+2$, than $p(-2) = 0$
•  Question 7: 2 pts Chose correct answer using the graph of the polynomial $p(x)$ (whose graph is shown in the figure).
 p(1)=2 p(-2)>0 p(3)>2 p(-4)<0
