1. ## Explanation

What steps should I do to calculate area?

Area of functions:
Example:
$\displaystyle y=x^3$, $\displaystyle x=0$ and $\displaystyle x=4$

2. I think the question should have $\displaystyle y=0$ too.

Did you make a sketch of the area? Do you have any idea about what to do?

1) Do functions have area?
2) You posted it the calculus section. You must have some clue.

We should take a poll. Is Apprentice123 really a student or is Apprentice123 just deliberately wasting time of volunteers because Apprentice123 is against any and all internet help sites?

What say you, Appretice123? Give us the first vote by actually showing your work and demonstrating some comprehension of something.

4. This is such a standard problem that I'm beginning to doubt that Apprentice123 even has a calculus textbook.

If $\displaystyle f(x) \geq g(x)$ on the interval $\displaystyle a < x < b$, then the area between the two curves is $\displaystyle \int_a^b (f(x)-g(x))dx$

In this case $\displaystyle g(x)=0$ (most likely, the post didn't give enough information) ...

5. What I would like to know is:

1) To find the points of the graph I do the intersection (equaling the y)

2) Or I do the derivative of the functions

The methods to construct the graph. Make the integral to calculate the derivative i know, I have problems only to build the graphics

This function that I did is just one example
