If the coefficient of x^3 is negative then the shape is a bit like the letter "S" pushed over from the left and then both free ends stretched out for ever.
Such a graph starts at the top left and goes down towards the bottom right with the gradient (slope) becoming steadily less steep. It can then move upwards for a short while before it continue its downward motion - only this time the gradient becomes steeper as you go along. Note that the upward bump may not be there (if there is a point of inflexion).
If the coefficient of x^3 is positive then the graph is a mirror image.

If a quadratic makes a parabola what is the name of the shape produced by a cubic function?
A cubic.
What is a graph of a cubic function called?
A cubic graph!
The function f(x) x3 is called the function?
The cubic function.
What do you called to the graph of a cubic function?
hyperbola * * * * * A hyperbola is not a cubic function. A cubic function is of the form y = ax3 + bx2 + cx + d where a, b, c and d are real constants and a is not 0. A hyperbola is a functon of the form y = 1/x : quite different.
The function f(x) x3 is called the?
Cubic.
