1. Pick 2 points with the same first value but different second values, ie (1,2) and (1,3)
2. Sketch a graph that does not pass the vertical line test.. that is you can draw a vertical line that passes through 2 points on your graph
3. 3/2
4. vertex is at point (2,-1) and goes through points (3,0) and (1,0)
5. y= (-1/2)x + 6.5
6. y = 3x/2 + (any number except 1)
7. -12
8. the range of ages.. maybe 0-100
9. 3x^2 – 4x + 5
10. 18x^3 – 27x^2 – 6x + 9
11. 48x^2 – 144x + 107
12. y = (x+3) / 2
13. y = 3 – (6x/5)
14. 6x^3 – 11x + x + 3
15. -1
16. The 3 is on the outside of the root sign and the 5 is on the inside.. x^5
17. (5/10)(5/10)(5/10)(5/26)(26/26)(5/26)
18. 4 < x < 6
19. (3x^7)/(5y^5) or (3x^7) / (5y^7)
20. x^(-31/15)
21. .0000000531
22. 2
23. 187.309 < x < 187.311
24. This is a function that as a different formula for y for different ranges of x. The domains cannot overlap
25. $3947
26. 4.429 cm
27. Enter values for the exponent t until you get a value of 2.5, or half of 5. The half life will be this t value
28. 7.186
29. Any polynomial with the highest exponent being 4.. it 3x^4 – 2x^3 …….
30. It will go down as x gets very large
