x > -10
Step-by-step explanation:
First subtract the 2 from both sides. This gets you to 5x > -50. Last, you divide both sides by 5 and get an answer of x > -10.
Answer:
zero: x = 0
discontinuities: x = -5, x = 5
Step-by-step explanation:
The zeros of the rational function will be found where the numerator is zero. That will happen when x=0.
__
There will be discontinuities where the denominator is zero. The denominator is the difference of squares, so factors as ...
x^2 -25 = (x -5)(x +5)
These factors will be zero when x=5 and x=-5.
