(a) Zeros: -2,0,4 Degree 3 (b) Zeros: -2, multiplicity 3; 1, multiplicity 1; degree 4 Guiding Question 3 Find a polynomial function that could form the graph shown below. Guiding Question 4 Use transformations of 4 y x = or 5 y x = to graph each function. ( 29 ( 29 ( 29 ( 29 ( 29 ( 29 ( 29 ( 29 5 4 5 3 3 1 2 a f x x b f x x c f x x = + = + = - -
