Then find the inverse function and list its domain and range. +1>0 (Example 7: (Given the logarithmic function ()=log1 3 See if you can work them out with some intelligent guesswork. What is domain and range? The domain and range of logarithmic functions are the subset of the real numbers for which it makes sense to evaluate the logarithmic function and the subset of real numbers {eq}y {/eq} for which . so the domain of an exponential function is the same as the range of a logarithmic function, and the range of an exponential function is the same as the domain of a logarithmic function. Find the domain of function f defined by: f (x) = ln (2 x 2 - 3x - 5) Solution to Example 5. The range of a function is the set of values that the function assumes. A logarithmic function with both horizontal and vertical shift is of the form (x) = log b (x + h) + k, where k and h are the vertical and horizontal shifts, respectively. Inverse: %=## Re-write as a log: !=log "% , where #>0,#1 The log of a number is the exponent to which a base must be raised to get .
