Question

Describe of the graph of function y=4x^3+16

Answer 1

Answer:

Graph the cubic using its end behavior and a few selected points.   Falls to the left and rises to the right.

Graph:

X  |  Y

-2 | -16

-1  | 12

0  | 16

1   | 20

2  |  48

Function of X:

To rewrite as a function of  x  f (x)  write the equation so that y   is by itself on one side of the equal sign and an expression involving only x   is on the other side.

F(x) = 4x^3 + 16.
