follow the steps below to sketch the graphic of the each polynomial function.

1. f(x)=x⁴+2x³- 4x²- 2x+3

2. f(x)=(x-2) (x-4) (x+1)

steps:
A. find the x intercept of the roots/zeros of the function.

B. make an interpretation of the x-intercept (cross or tanget)

C. find the y-intercept of the function

D. describe the end behaviors of the graphs

E. construct the table of values

F. determine the number of turning points

G. sketch the graph use graphing paper
