What is an Inverse Function?

An inverse function reverses the operation of the original function. Key properties:

• Denoted as f⁻¹(x)
• f(f⁻¹(x)) = x and f⁻¹(f(x)) = x
• Only exists for bijective functions
• Graph is reflection of original function over y=x line

Common Inverse Function Types

Function Type	Example	Inverse
Linear	f(x) = 2x + 3	f⁻¹(x) = (x-3)/2
Exponential	f(x) = e^x	f⁻¹(x) = ln(x)
Logarithmic	f(x) = log(x)	f⁻¹(x) = 10^x
Trigonometric	f(x) = sin(x)	f⁻¹(x) = arcsin(x)

Key Features

• Supports multiple function types
• Step-by-step solutions
• Variable selection
• Mathematical symbol keypad
• Error checking system
• Mobile-friendly design

Frequently Asked Questions

Can all functions be inverted?

Only bijective functions (both injective and surjective) have true inverses. Some functions require domain restrictions.

How do you verify inverse functions?

Verify that f(f⁻¹(x)) = x and f⁻¹(f(x)) = x for all x in the appropriate domains.

What’s the inverse of a quadratic function?

Quadratic functions require domain restrictions. For f(x) = x² (x ≥ 0), the inverse is f⁻¹(x) = √x.

Can I find inverses of trigonometric functions?

Yes, but they require specific domain restrictions. For example, sin⁻¹(x) has domain [-1, 1] and range [-π/2, π/2].
