Describe the end behavior of the graph of the polynomial function. Then evaluate the function for x=4, 3, 2, 1, 0, 1, 2, 3, 4. Then graph the function.y=x^42x^2x1 and y=(x3)(x+1)(x+2)

Did you try just following the instructions?
They seem pretty straightforward.
For the end results, try ± large values
e.g. let x=1000 and x = 1000
wouldn't both x^4 become huge for both values, so what happens to the y value at those farout values of x ?
notice that the second function starts with y = x^3 ...
when x = 1000 , y = +1000000000
when x = 1000 , y = (1000)^3 = 1000000000
what does that tell you about the position of y for huge negative values of x ?
