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

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.

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.
