# How do I find the domain of a log?

The logarithmic function, y=logbx , can be shifted k units vertically and h units horizontally with the equation y=logb(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=lnf(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.
