How to Use the F of G Calculator

Using the calculator is simple and user-friendly:

Step 1: Enter Function f(x)

Input the outer function (for example: f(x) = x² + 3)

Step 2: Enter Function g(x)

Input the inner function (for example: g(x) = 2x + 1)

Step 3: Enter Value of x

Provide the value for x (for example: x = 2)

Step 4: Click Calculate

The calculator instantly computes:

• g(x)
• f(g(x))

Practical Example

Let’s understand with an example:

• f(x) = x² + 3
• g(x) = 2x + 1
• x = 2

Step 1: Calculate g(x)

g(2) = 2(2) + 1 = 5

Step 2: Calculate f(g(x))

f(5) = 5² + 3 = 25 + 3 = 28

Final Result:

f(g(2)) = 28

The calculator performs this instantly.
