Answer:
It’s 4
Step-by-step explanation:
F(0)=4-8x
f(0)=4-8(0)
f(0)=4
1/7x
Factorize the numbers (4 and 28) as they have a common factor of 4 so you can simplify it to 1/7. Cancel out the 3 in the x (numerator) from the denominator and you will have x^1 remaining in the denominator. That is also the same as x, therefore making it 1/(7x)
The vertical asymptote is the located in the denominator, so (x-4)=0, x=4, the asymptote is x=4, and the limit is negative infinity
M = (N-2)/N
M = N² - 2N
N² - 2N - M = 0
To find N we need to use quadratic formula.
For our equation x = N, a=1, b= -2, c= -M
