Topic C: Graphs of Common Functions Sketch each of the following as accurately as possible. You will need to be VERY familiar with each of these graphs throughout the year. You may use a graphing calculator for some of them if you have access to one over the summer. On the first day of class, you will be given a TI-Nspire to use (you could finish the last few then). Another option is to find a graphing app or generate a table of values. Again, these are VERY important graphs to know. Be very accurate with regards to “open circles” and “closed circles.” 1. y x 2. y x 2 3. y x3 4. y x 5. y x 6. y x x 7. y x 1 8. y x 3 9. y sin x 2 3 10. y cos x 13. y sec x 14. y csc x 12. y cot x 11. y tan x 15. y e x 16. y ln x 17. y 1 x 18. y x 19. y 1 x2 20. y 2 x 21. y 4 x 2 22. y sin x x Topic D: Even/Odd Functions and Symmetry Show work to determine if the relation is even, odd, or neither. 1.) f x 7 2.) f x 2 x 2 4 x 4.) f x 7.) y 8 x x 1 1 8x 5.) f x x2 1 8.) f x 8x 3.) f x 3x3 2 x 6.) f x 8x 9.) f x 8x 8x Show work to determine if the graphs of these equations are symmetric to the x-axis, y-axis, or the origin. 10.) 4 x 1 11.) y 2 2 x 4 6 12.) 3x 2 4 y3 13.) x y 14.) x y 15.) x y 2 2 y 1 Topic E: Function Transformations If f x x 2 1 , describe in words what the following would do to the graph of f x : 1.) f x 4 2.) f x 4 3.) f x 2 4.) 5 f x 3 5.) f 2 x 6.) f x Sketch the following graphs: 7.) y 2 f x 8.) y f x 9.) y f x 1 10.) y f x 2 11.) y f x 12.) y f Here is a graph of y f x : x Topic F: Special Factorization Factor completely. 1.) x3 8 2.) x3 8 3.) 27 x3 125 y 3 4.) x4 11x2 80 5.) ac cd ab bd 6.) 2 x 2 50 y 2 20 xy 7.) x 2 12 x 36 9 y 2 8.) x3 xy 2 x 2 y y 3 9.) x 3 2 x 1 x 3 2 x 1 2 3 3 2 Topic G: Linear Functions 1.)
