lim t+2/t-5

t-->5-

- Find the limit -
**jai**, Thursday, October 28, 2010 at 10:59pmfirst, we observe what happens when t approaches 5:

lim (t+2)/(t-5) as t->5

7/0 = infinity

which can be (+) or (-) infinity

since it's 5- or to the left of 5, some of the values can be 4.99, 4.999, 4.9999,, if we choose for instance, 4.999,

4.999 - 5 = -0.001 *negative*

thus, the lim (t+2)/(t-5) as t->5- is

(-) infinity
