How do you find the domain, range, x-int, and vertical asymptote for a log function? - vertical log homes
I do not know how. can someone give me an example?
Thank you.

Vertical Log Homes How Do You Find The Domain, Range, X-int, And Vertical Asymptote For A Log Function?

f (x) = x ln (base e)
Dom f (x) = R> 0 . . Range of f (x) = R
x - int p = (1, 0)
V. Ace x = 0
g (x) = logx (base 10)
Dom g (x) = R> 0 . . Range of G (x) = R
x - int p = (1, 0)
V. Ace x = 0

EX1:
f (x) = log (x ² -1)
Domain (f): x ² -1> 0, | x |> 1
Range (f): (-inf, + inf)
vertical asymptote: solve x ² -1 = 0, x =- 1.1: VA
Ex2:
f (x) = 2ln (| x |)
a - The domain of f is the set of all values of x such that
| X |> 0
The area is to all real numbers except 0
The range of f is the interval (-inf, + inf).
b - The vertical asymptote is obtained by solving
| X | = 0
give
x = 0
f (x) = log (x)
Domain: all real numbers that is greater than 0.
Since the logarithm of a negative number is undefined, x> 0
Range: all real numbers [which is (- ∞, ∞)]
To the point of intersection x, y = 0
log (x) = 0
x = 1 so that (1.0) is the intersection x
Vertical Asymptote:
If log (x) to infinity (or minus infinity)?
If x = 0 and x = 0, the vertical asymptote is.
