1. Evaluate the Given limit:

Solution:

Given

Substituting x = 3, we get

= 3 + 3

= 6

2. Evaluate the Given limit:

Solution:

Given limit:

Substituting x = π, we get

= (π – 22 / 7)

3. Evaluate the Given limit:

Solution:

Given limit:

Substituting r = 1, we get

= π(1)2

= π

4. Evaluate the Given limit:

Solution:

Given limit:

Substituting x = 4, we get

= [4(4) + 3] / (4 – 2)

= (16 + 3) / 2

= 19 / 2

5. Evaluate the Given limit:

Solution:

Given limit:

Substituting x = -1, we get

= [(-1)10 + (-1)5 + 1] / (-1 – 1)

= (1 – 1 + 1) / – 2

= – 1 / 2

6. Evaluate the Given limit:

Solution:

Given limit:

= [(0 + 1)5 – 1] / 0

=0

Since, this limit is undefined

Substitute x + 1 = y, then x = y – 1

7. Evaluate the Given limit:

Solution:

8. Evaluate the Given limit:

Solution:

9. Evaluate the Given limit:

Solution:

= [a (0) + b] / c (0) + 1

= b / 1

= b

10. Evaluate the Given limit:

Solution:

11. Evaluate the Given limit:

Solution:

Given limit:

Substituting x = 1

= [a (1)2 + b (1) + c] / [c (1)2 + b (1) + a]

= (a + b + c) / (a + b + c)

Given

= 1

12. Evaluate the Given limit:

Solution:

By substituting x = – 2, we get

13. Evaluate the Given limit:

Solution:

Given

14. Evaluate the given limit:
