How to find the limit of that question
jeka94
Factor the numerator using difference of cubes:
a^3 - b^3 = (a-b)(a^2 +ab+b^2)
a = x
b = 2

\frac{x^3 - 8}{x-2} = \frac{(x-2)(x^2 +2x+4)}{x-2} = x^2 +2x+4

Now you can evaluate limit as x=2.
\lim_{x \to 2} (x^2 +2x+4) = 2^2 +2(2)+4 = 12

Graph on the number line all values of x that satisfy 2x+2/x+7 >= 0
LiRa [457]

All values of x that satisfy 2x+2/x+7 >= 0 are represented as x >= -1

<h3>How to graph the inequality on a number line?</h3>

The inequality expression is given as:

2x+2/x+7 >= 0

Multiply both sides by x + y

2x+2 >= 0

Subtract 2 from both sides

2x > -2

Divide both sides by 2

x >= -1

Hence, all values of x that satisfy 2x+2/x+7 >= 0 are represented as x >= -1

See attachment for the number line of x >= -1
