4. Identify all the graphs in the diagrams below. (3,1000) 0 y x (0,1)  0 y 1 (2,0.25) x  (16,2) 1 0 y  x 1  (2,16) 0 y (1,-5) (10,-4) x   0 y -3 (6,1) x  0 y 1 (1,6) x 

5. 0 y 1 (2,0·25) x  0 y (9,1) x  Identify all the graphs in the diagrams below. (5,1) 1 0 y  x 4  (1,2) 0 y (9,5) x  4 (2,10) (0,2) 0 y x  0 y 1 (3,8) x 

6. Identify all the graphs in the diagrams below. 0 y (1,1) x   (10,2) 0 y (1,3) x   (10,4) 0 y (1,-1) x   (10,0) 0 y (2,0) x   (11,1) 0 y (3,0) x   (12,1) 0 y (-2,0) x   (7,1)

7. 1. y = 4 x 2. y = 5 x 3. y = 2 x 4. y = (1/3) x 5. y = (1/10) x 6. y = 6 x 7. y = 10 x 8. y = 0.5 x 9. y = 4 x, y = log 4 x 10. y = logx-511. y = log(x+4)12. y = 6 x 13. y = 0.5 x 14. y = log(x+1)15. y = 2 x, y = log 2 (x-3) 16. y = log(x+1)+317. y =3 x + 118. y = 2 x 19. y = logx + 120. y = logx + 321. y = logx - 1 22. y = log(x-1)23. y = log(x-2)24. y = log(x+3) Answers
