Answer:
There is a vertical asymptote at x = 4 because lim g(x) = ∝ and lim g(x) = -∝
The existence proof of the empty set is an absolute gem
So first, you get the absolute value to one side:

Next, set up two equations; One where the value inside the absolute value lines is positive, and another where it is negative, and solve both for the variable:

Your answers are
8 and -8, or +-8.
U . v = |u| . |v| cos 60 = 10 * 8 * 0.5 = 40 This is called the scalar (or dot) product.
Answer:
The answer is x=5 and x=−5
x² - 25 = 0
(x-5)(x+5)=0
x²-5x+5x-25=0
x-5=0 x+5=0
x=5 or x=-5
