[tex]\\ \sf\bull\dashrightarrow {\displaystyle{\lim_{x\to c}}}\dfrac{p(x)}{q(x)}=\dfrac{0}{1}=0[/tex]
- The limit tends to 0
- Hence c=0
[tex]\\ \sf\bull\dashrightarrow {\displaystyle{\lim_{x\to c}}}\dfrac{p(x)}{q(x)}=\dfrac{1}{1}=1[/tex]
- Here limit tends to 1
- Hence c=1
[tex]\\ \sf\bull\dashrightarrow {\displaystyle{\lim_{x\to 0}}}\dfrac{p(x)}{q(x)}=\dfrac{1}{0}=\infty[/tex]
- Here x tends to infty.
- c=infty
For the fourth one limit also tends to zero
