Question

I have a few questions I need help with involving limits and continuous functions.

Since they all have equations it will take me a minute or two to type all the equations up and post!

Answer 1

find the value of c such that \[\lim_{x \rightarrow c ^{+}} \frac{ 6 }{ (x-2)(7-x)}=-\infty\]

Answer 2

why dont you graph f(x) = 6 / [ (x-2)(7-x)] first

Answer 3

c = 7 works

Answer 4

The expression becomes infinity when the denominator gets to zero.
There are two values of x that will make the denominator zero.
Which value when approached from the left will yield NEGATIVE infinity?

Answer 5

I meant "approached from the right"
