This f of g calculator allows you to easily compute the composition of two functions, providing you with precise mathematical results.

## f of g Calculator

### How to Use This Calculator

- Input the function
**f**in terms of**x**in the first field. - Enter the function
**g**also in terms of**x**in the second field. - Type in the numerical value for
**x**in the third field. - Press the “Calculate” button to get the result of
**f(g(x))**.

### How it Calculates the Result

This calculator first evaluates g(x) with the provided x value, then substitutes this result back into f(x) to finally compute f(g(x)). Please use standard mathematical syntax, for example, use ‘^’ for exponentiation (e.g., x^2 for x squared).

### Limitations

The calculator does not support implicit multiplication (e.g. 2x should be written as 2*x) and relies on correct input syntax. It also cannot handle functions beyond basic algebraic operations. Division by zero, undefined mathematical operations, or functions with discontinuities may not yield correct results.
