<PRE><B>Question 1172358</B>
Find all the zeros of the polynomial function by graphing on the calculator to narrow down the real solutions, then use synthetic division until you get a quadratic to solve.  Solve the quadratic equation to complete the list of zeros.
7.  h(x) = x^3 − 3x^2 − x + 3			

8.  f(x) = x^4 − 4x^3 − 20x^2 + 48x

9.  g(x) = x^3 + 5x^2 + x + 5
			
10.  g(x) = x^4 − 9x^3 + 23x^2 − 81x + 126
