consider a right angle where one vertex is on the graph of f(x) = x cubed, another on the y axis, and the third at the orgian. write an equation for the area of the triangle in terms of x 

To solve this problem, we need to express the area of a right triangle in terms of \(x\), given the constraints.

### Step-by-Step Solution:

1. **Coordinates of the Points:**
   - The third vertex is at the **origin**, so its coordinates are \((0,0)\).
   - The vertex on the graph of \(f(x) = x^3\) is at \((x, f(x)) = (x, x^3)\).
   - The vertex on the **y-axis** lies on the y-axis at some point \((0, y)\), and we need to determine its exact location.

2. **Using the Right-Angle Condition:**
   The right triangle has one leg along the y-axis and the other leg along the horizontal line. Thus, the horizontal distance from the point on the graph \((x, x^3)\) to the y-axis is \(x\), and the vertical distance from the point on the graph to the x-axis is \(x^3\).

3. **Area of the Triangle:**
   The area \(A\) of a right triangle is given by:
   \[
   A = \frac{1}{2} \times \text{base} \times \text{height}
   \]
   In this case:
   - The base of the triangle is the horizontal distance between the point on the graph \((x, x^3)\) and the y-axis, which is \(x\).
   - The height of the triangle is the vertical distance between the point \((x, x^3)\) and the x-axis, which is \(x^3\).

   So the area of the triangle becomes:
   \[
   A(x) = \frac{1}{2} \times x \times x^3 = \frac{1}{2} x^4
   \]

### Final Equation for the Area:
The area of the triangle in terms of \(x\) is:
\[
A(x) = \frac{1}{2} x^4
\]
