evaluate the limit as x approaches 1 for f(x)

**Damon**, Saturday, September 29, 2012 at 7:06pmthe left is undefined as x >> 1

but for any other x very close to x = 1

f(x) - 7 = 8(x-1)

for example if x = .99

f(.99) - 7 = 8(.99-1) = 8 (-.01) = - .08

f(.99) = 7 -.08

which might give us a hint as to where f(x) was going :)

in fact it looks to me like

f(x) - 7 = 8(x-1)

is similar to

f(x) = 7 + 8(x-1)

and as x >>1

f(1) =7 +8(0) = 7
