Concordia MATH 201 tutoring
Elementary Functions — one-to-one online tutoring to understand difficult concepts, practise problems and prepare for midterms and finals.
Listed course
Course overview
Concordia MATH 201 studies power, polynomial, rational, algebraic, exponential, logarithmic, and trigonometric functions. It emphasizes graphs, transformations, inverses, composition, and trigonometric relationships.
MATH 201 topics we can help with
Function notation and compositionGraph transformationsPolynomial and rational functionsExponential functionsLogarithmic functionsTrigonometric functions
Common difficulties
- Tracking the domain through a composition
- Distinguishing an inverse function from a reciprocal
What this course builds on
Review factoring, equation solving and coordinate graphs. Function composition, inverses and domains build on those tools.
Registration requirements
No formal course prerequisite is listed in the current calendar; MATH 200 is useful preparation, not a stated mandatory prerequisite.

Simplify (x² − 16)/(x − 4) and state the restriction.
Show the reasoning
x + 4, for x ≠ 4. Cancelling the common factor does not restore the excluded input.

How tutoring can help
Connect each function formula to a domain, sketch and transformation. Use inverse operations to explain logarithms before practising equations.
Exam preparation for MATH 201: midterms and finals
For each function family, practise formula, domain, sketch and transformation. Mix logarithmic and trigonometric equations so you must choose the method.
Use your section’s outline to choose the chapters to review. We work through permitted practice and comparable problems, without completing graded assignments or exams on your behalf.
