Question

Find the limit of the function by using direct substitution lim (x^2+8x-2) x-> 2

Answer 1

Answer:

$lim_{x \to 2} x^2 +8x -2$

And using the properties of limit we got:

$lim_{x \to 2} x^2 +8 \lim_{x \to 2} x - lim_{x \to 2} 2$

And replacing we got:

$2^2 + 8 (2) -2 = 4 +16-2 =18$

Step-by-step explanation:

For this case we want to find this limit:

$lim_{x \to 2} x^2 +8x -2$

And using the properties of limit we got:

$lim_{x \to 2} x^2 +8 \lim_{x \to 2} x - lim_{x \to 2} 2$

And replacing we got:

$2^2 + 8 (2) -2 = 4 +16-2 =18$
