Rational Functions — IB Maths AA HL Practice
Rational functions are all about asymptotes and intercepts. Practise vertical and horizontal asymptotes, intercepts and the HL oblique asymptote — with a worked example on every miss.
The idea
What you'll master
- Vertical asymptote
- Horizontal asymptote
- Intercepts
- x-intercept
- Oblique asymptote
Sample questions
- State the vertical asymptote of $y=\dfrac{3x+5}{x-5}$ (give the $x$-value).
- State the horizontal asymptote of $y=\dfrac{6x+5}{2x-4}$ (give the $y$-value).
- Find the $y$-intercept of $y=\dfrac{4x+2}{x-6}$.
Every attempt generates new numbers — the practice below never runs out.

Frequently asked questions
Is this IB Maths AA HL rational functions practice free?
You can read the method and try the sample questions here for free. Unlimited rational functions practice is part of the full Photon Learning Studio — a one-time SGD 250 unlocks every topic.
How is this different from past-paper practice?
Every question is generated fresh at exam standard. When you get one wrong it re-teaches that exact skill — a hint, then a fully worked example of the same type, then a step-by-step walkthrough — so you build the method, not just memorise answers.
Who is Photon Learn for?
