**logarithmic**function, y=

**log**bx , can be shifted k units vertically and h units horizontally with the equation y=

**log**b(x+h)+k . Then the

**domain**of the function becomes {x∈ℝ|x>−h} .

In this manner, how do you find the domain of a function?

For this type of **function**, the **domain** is all real numbers. A **function** with a fraction with a variable in the denominator. To find the **domain** of this type of **function**, set the bottom equal to zero and exclude the x value you find when you solve the equation. A **function** with a variable inside a radical sign.

Likewise, what is the property of log? Logarithm of a Product Remember that the **properties** of exponents and **logarithms** are very similar. With exponents, to multiply two numbers with the same base, you add the exponents. With **logarithms**, the logarithm of a product is the sum of the **logarithms**.

Similarly, it is asked, how do you find the domain and range of a Ln function?

The answers are: D(6,+∞) and R(−∞,+∞) . The **domain** of the **function** y=**ln**f(x) is: f(x)>0 . The **range** of a **function** is the **domain** of the inverse **function**. The inverse **function** of the logarithmic **function** is the exponential **function**.

What is the domain and range?

Because the **domain** refers to the set of possible input values, the **domain** of a graph consists of all the input values shown on the x-axis. The **range** is the set of possible output values, which are shown on the y-axis.
