This video tutorial provides a review on how to find the domain and range of a function using a graph and how to write or express it using interval notation. This video is for those who may be taking algebra 1 or 2, trigonometry, precalculus or calculus and who wants to have a solid foundation on determining the domain and range of an equation. This video contains plenty of examples and practice problems.

1. Domain and Range of a Graph – Closed and Open Circles – Parentheses vs Brackets

2. Piecewise Function / Graph – Continuous and Discontinuous Functions

3. Writing the Domain and Range Using Interval Notation

4. Horizontal and Vertical Assymptotes Including Holes

5. Linear Functions and Equations – Slope Intercept Form

6. Domain and Range of Quadratic Functions / Equations and Parabolas

7. Domain and Range of a Cubic Function

8. Polynomial Functions – Domain – All Real Numbers

9. Parent Functions and Transformations – Horizontal & Vertical Shifts Plus Reflection About X and Y Axis

10. Domain and Range of Radical Functions – Square Root and Cube Root

11. Using a Number for the domain and range of a square root function

12. Rational Functions – Fractions, Horizontal, Vertical, Slant / Oblique Assymptotes

13. Absolute Value Functions and Equations

14. Domain and Range of Exponential and Logarithmic Functions

15. Domain and Range of Trigonometric Functions

16. Trig Equations – sin cos tan

17. Domain of Sine and Cosine – All Real Numbers

18. Range of sine and cosine – Restrictions – Amplitude and Midline

19. Range of Tangent Function – All Real Numbers

Tried out the canvas response option on @SpiralEducation & it's so awesome! Add text or drawings AND annotate an image! #R10tech

Using @SpiralEducation in class for math review. Student approved! Thumbs up! Thanks.

Absolutely amazing collaboration from year 10 today. 100% engagement and constant smiles from all #lovetsla #spiral

Students show better Interpersonal Writing skills than Speaking via @SpiralEducation Great #data #langchat folks!
