For each given polynomial function, describe or determine the following
a. leading term b. end behaviors c. zeros
d. multiplicity of zeros f. number of turning points g. sketch
1. y = – (x + 3)(x + 1)2(2x – 5)
2. y = (x –5)2 (x–1)2 (x–2)3
3. y = (x +2)4 (x –1) (x –3)2
4. y = x(x – 2) (x + 1) (x +3)2
