Question

Find the limit.

lim as x approaches 0

(x^3+12^2-5x)/(5x)

a) 5 b) -1 c) 0 d) does not exist

Answer 1

are you sure it is 12^2 in the numerator .??

Answer 2

plug in x=0 to top and bottom, what do you get ?

Answer 3

it will be undefined because the denominator becomes \[zero\]

Answer 4

*12x^2

Answer 5

\[-1\]

Answer 6

thanks!

Answer 7

yeahh ..12x^2 is better ..:))
divide the numerator and denominator by x
and then plug into the limit

Answer 8

the answer must be -1

Answer 9

take out x on top to remain with\[\frac{x(x ^{2} +12x -5)}{ 5x }\]
cancel out x on top and bottom, and the plug in zero in place of x. You will remain with
\[\frac{ -5 }{ 5 } = -1\]
