Domain And Range Of The Function Y Log X
When finding the domain of a logarithmic function therefore it is important to remember.
Domain and range of the function y log x. In case the base is not 10 for the above logarithmic functions domain will remain unchanged. 0 0 set builder notation. That is all real numbers.
Graphing a logarithmic function with a horizontal shift logarithmic functions with a horizontal shift are of the form f x log b x h or f x log b x h where h the horizontal shift. X x 0 x x 0. Y log x y log x set the argument in log x log x greater than 0 0 to find where the expression is defined.
In graphs of exponential functions we saw that certain transformations can change the range of latex y b x latex. The function y log 5 x will also have 0 infinity and infinity infinity as the domain and range respectively. The table shown below explains the range of y log 10 x.
X 0 x 0. Therefore the domain of the logarithmic function y log b x is the set of positive real numbers and the range is the set of real numbers. For example in the logarithmic function.
X 0 or 0 range of logarithmic functions. Y log 10 x instead of base 10 if there is some other base the domain will remain same. The domain is all values of x x that make the expression defined.
