Example: Find the domain and range of the logarithmic function f (x) = 2 log (2x - 4) + 5. Solution: For finding domain, set the argument of the function greater than 0 and solve for x. Thus, domain = (2, ∞). As we have seen earlier, the range of any log function is R. So the range of f (x) is R.

In this section, you will learn how to find domain and range of logarithmic functions. The table shown below gives the domain and range of different logarithmic functions.

Here, we will learn how to determine the domain and range of logarithmic functions. In addition, we will look at some examples with the graphs of the functions to illustrate these ideas.

To find domain of logarithmic function, we can use the procedure given below. Step 1 : Take the argument and create the condition, (ax + b) > 0. Step 2 : Get the possible values of x from the above condition. For example, Range : Set of possible values of y is range. Always all real values. Identify the domain and range of each. Domain is (1, ∞).

Find the domain and range of the function y = 3 x + 2 . Graph the function on a coordinate plane. The graph is nothing but the graph y = 3 x translated 2 units to the left. The function is defined for all real numbers. So, the domain of the function is set of real numbers.

Before working with graphs, we will take a look at the domain (the set of input values) for which the logarithmic function is defined. Recall that the exponential function is defined as y = bx y = b x for any real number x and constant b>0 b> 0, b≠ 1 b ≠ 1, where. The domain of y is (−∞,∞) (− ∞, ∞). The range of y is (0,∞) (0, ∞).
