Find the domain, range, inverse, or composition of any function step-by-step on AskSia. Every solve graphs the function with intercepts, asymptotes, and key points labeled, so the algebra finally matches the picture.
The AskSia function solver is an AI tool that analyzes any function f(x): finding its domain, range, inverse, composition with another function, and key behavior (one-to-one, even, odd, increasing, decreasing, bounded). Every solve returns a step-by-step worked solution with the function graphed and intercepts, asymptotes, and turning points labeled. Useful for Algebra 2, Pre-Calc, and Calc 1, where function analysis is the foundation for everything that follows.
Domain, range, inverse, composition, transformations, one-to-one. AskSia handles every question your textbook asks about a function, with the graph drawn so the answer makes visual sense.
AskSia identifies every restriction: division by zero, even roots of negatives, log of non-positives, and combinations of these. The domain is given in interval notation and set notation, with the excluded points labeled on the graph.
Range is found by analyzing the function's behavior: maximum and minimum values, asymptotes, end behavior. AskSia shows both the algebraic argument and reads the range off the graph for confirmation.
To find f-inverse(x), AskSia swaps x and y, solves for y, and checks the result by composing f with f-inverse and showing it equals x. The original and inverse functions are both graphed, with the line y = x for reference.
(f composed with g)(x) is computed by substituting g(x) into f wherever x appears. AskSia shows the substitution clearly, simplifies, and notes which composition is associative or commutative.
Shifts (horizontal, vertical), stretches (vertical, horizontal), and reflections (over x-axis, y-axis) are identified from the function's form. AskSia graphs both the parent and transformed functions side-by-side.
Piecewise functions and absolute-value functions are handled with each piece evaluated and graphed separately. Open and closed dots are placed correctly at the boundary points.
Snap a photo, paste the function, or type it into the built-in calculator. AskSia reads any notation, including piecewise definitions and absolute values.
Tell Sia what you need: domain, range, inverse, composition, or a specific transformation. AskSia handles each request with its own step-by-step worked solution.
AskSia auto-generates the graph with intercepts, asymptotes, and key points labeled. The algebraic answer appears alongside, with a visual confirmation.
Every solve syncs across Web, iOS, and Android — start it at your desk, finish on your phone.
Split-panel interface with the worked solution on the left, the auto-generated diagram and AI tutor chat on the right.
Open the camera, frame the problem, and the worked solution plus diagram appear in seconds.
First-time function topics: domain, range, evaluating f(a), function notation. AskSia walks through each step clearly, with the graph showing what's happening.
Inverse functions, composition, transformations, even and odd, one-to-one tests. The full Pre-Calc function unit, with graphs and algebra paired on every solve.
Calc 1 starts with limits of functions, which assumes solid function analysis. AskSia covers the function side completely so the calculus lands on solid ground.
Piecewise functions with multiple pieces, each on its own interval. AskSia evaluates each piece, graphs them together, and places open and closed dots at boundary points.
Given y = a f(b(x minus h)) + k, identify the shift, stretch, and reflection. AskSia graphs the parent function and the transformed function side-by-side, with each operation labeled.
Function problems are SAT and ACT regulars and AP staples. After any solve, generate practice problems at the right difficulty level for your target exam.
