Question
Let f(x):
What is the equation of the vertical asymptote of f(x) and what is the sign of f(x) as
x - 5x +6
x approaches the asymptote from the right?
x = 3, negative
b.
x = 2, negative
а.
с.
x = 3, positive
d.
x = 2, positive
If f(x) is decreasing for every x > 5, then which choice is not a possibility for f '(x)?
a. f'(x) = 5-x
b. f'(x) = -x² + 10x – 25
c. f'(x) = x - 5
d. f'(x) = -5
