Question

Determine the infinite limit. lim x→−9− x + 8 x + 9

Answer 1

If given
$\lim_{x \to \ -9} (-x+8x+9)$
then
$\lim_{x \to \ -9} (-x+8x+9)=-54.$

Answer 2

Following are the calculation to find the limit:

Given:

$\lim_{x \to -9}\ (-x + 8 x + 9)$

To find:

value=?

Solution:

$\lim_{x \to -9}\ (-x + 8 x + 9)$

applying the limit.

$\to (-(-9) + 8 (-9) + 9)\\\\\to (+9 -72 + 9)\\\\\to -54$

Therefore, the final answer is "-54".
