Find the limits using first principle:

1. lim (3x-1)5 (NB 5 is subscript)

x® -1

2. limÖx-2(NB this is the square root of x -2)

x®4 x-4

Find the limits algebraically:

4. limx-2

x®2 x3-8 (NB this is x cubed -8)

5.lim (x2-1) (NB this is x squared)

x® 1 x-1 x-1

6.lim1

x® 8- x-8

7. lim1

x® 8+ x-8

8. lim1

x®8 x-8
