I believe you're asking about the one-sided limit,
Recall the definition of absolute value:
• 
if 
• 
if 
Since we're approaching -4 from the left, we're effectively focusing on a domain of 
or 
. So, by the definition above, we have 
. Then in the limit, we have
Answer:4x -9 >= -21
4x >= -12
x >= -12/4
x >= -3
so this number line started with -3 and go away till + infinity
hope this will help you
To find the zeros of this equation you need to first set it equal to zero
2x2 + 16x - 9 = 0
But since you can't FOIL this equation you need to move the non-variable number over
2x2 +16x = 9
Now solve for x by pulling an x out of the equation
x(2x + 16) = 9
x = 9
2x +16 = 9
2x = -7
x = -7/2
So your zeros would be at x = 9, and -7/2
