Factor the numerator using difference of cubes:
a = x
b = 2
Now you can evaluate limit as x=2.
a = x
b = 2
Now you can evaluate limit as x=2.
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
