Find the limit of the function by using direct substitution as X approaches one lim(x^2-8x -2)
Leno4ka [110]

Answer:

lim_{x \to 1} x^2 -8x -2 =-9

Step-by-step explanation:

For this case we want to find the following limit:

lim_{x \to 1} x^2 -8x -2

And we can find the limit distirbuting into each term like this:

\lim_{x \to 1} x^2 -8 lim_{x \to 1} x -lim_{x \to 1} 2

And replacing we got:

1^2 - 8*1 -2 = 1-8-2 = -9

So then the final answer for this case is:

lim_{x \to 1} x^2 -8x -2 =-9
