2. Click the ‘Calculate’ button.
3. View the result below the calculator.

Formula & Methodology

The calculation performed by this tool is based on the formula: f(x) = x^n. Here’s a step-by-step breakdown:

1. Take the input value ‘n’.
2. Calculate x^n for x values ranging from -10 to 10.
3. Plot the points on a graph.

Real-World Examples

Case Study 1: n = 2

The function f(x) = x^2 represents a parabola opening upwards. It’s used in physics to model projectile motion.

Case Study 2: n = 3

The function f(x) = x^3 is used in engineering to model the volume of a cube.

Case Study 3: n = 0.5

The function f(x) = x^0.5 (or √x) is used in mathematics to find square roots.

Interactive FAQ

What happens when n = 0?

When n = 0, the function f(x) = x^0 is undefined for x = 0, and equals 1 for all other x.

What happens when n is a fraction?

When n is a fraction, the function represents a root or power function. For example, n = 0.5 represents a square root.
