1.Graph the function f(x) = (x + 3)3 by hand and describe the end behavior

Answer 1

F(x) = Y = 3(x+3) = 3x+9.
Graph the function using the given points:

(-3,0) , (-2,3) ,(0,9) , (1,12).
The graph of this Eq is very odd.
You would expect to get a st. line, but the graph resembles an X-parabola.

If you draw a vertical line through the graph, it will intersect the graph
twice. A function should intersect the line only once. Therefore, the Eq does
not qualify as a function.

Answer 2

3. Graph the function f(x) = –3x3 + 9x2 – 2x + 3 using graphing technology and describe the end behavior.
