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.
