# How Does Someone Find the Domain of Logarithmic Functions?

The domain of logarithmic functions can be found by finding all of the numbers that do not make the value of y imaginary. The domain of the function can be deducted by taking out all of the numbers that work to make the y function an imaginary one.

A logarithmic function is one in which the exponents are inversed. For example, y = b^x would be x = b^y when it is inverse. This can be used to solve what y is in any type of logarithmic function. The values of x and the values of b must be the only things known to find out what the value of y is with the help of a calculator.

It is possible to find the value of y by hand in logarithmic function, but it can be difficult and take a long period of time. More commonly, a calculator with a LOG function on it is used to find the logarithmic domain of y. To find the logarithmic domain of any number in a sequence, the number can be plugged into the calculator followed by the LOG key. If a person wishes to find the inverse option of the logarithmic domain, he must use the LN key.
