what is the inverse function of ln x?
534946
Inverse function of ln(x) is the exponential function (e^x). Trying to be more clear, For an inverse function the domain of original function becomes the range of inverse function and the range of original function becomes the domain of inverse function.

In the math example, the steps are to multiply by 8 and take the cube root. The inverse operations in reverse order are to cube and divide by 8. Take x, cube to get x3 and divide by 8 to get x3/8. This x3/8 is called the inverse function and is written as f-1 (x).

In mathematics, the logarithm is the inverse function to exponentiation. That means the logarithm of a given number x is the exponent to which another fixed number, the base b, must be raised, to produce that number x.

Given the function f(x) we want to find the inverse function, f−1(x) f − 1 ( x ) . First, replace f(x) with y . This is done to make the rest of the process easier. Replace every x with a y and replace every y with an x .

['To find an inverse function reflect a graph of a function across the y=x line and find the resulting equation. This can also be done by setting y=x and x=y. ... ', 'now switch the x and y variables to create the inverse functions. ... ', 'This function when solved for y will be the same as the following.']

Douglas K. Usually log(x) means the base 10 logarithm; it can, also be written as log10(x) . ... ln(x) means the base e logarithm; it can, also be written as loge(x) . ln(x) tells you what power you must raise e to obtain the number x.

Getting the inverse of a function is simply switching the x and the y, plotting the new graph (or doing the algebra to get the “new” y), and seeing what you get! ... We use the inverse notation {{f}^{{-1}}}\left( x \right) to say we want the “normal” (x) value back when (y) is a certain number or expression.

The general form of an invertible, linear function is y=ax+q(a≠0) and its inverse is y=1ax−qa. The y-intercept is obtained by letting x=0: y=1a(0)−qay=−qa. This gives the point (0;−qa).

A function f is self-inverse if it has the property that f(f(x))=x. for every x in the domain of f. In other words, f(x)=f−1(x). For example, 1x and 3−x are self-inverse.

The anti-logarithm (or inverse logarithm) is calculated by raising the base b to the logarithm y: x = logb-1(y) = b y.

Since the function is both, one to one and on-to function, then f(x) is bijective. If f(x) is bijective => f(x) is invertible. The requested inverse function of f(x) = 3x + 12 is: f^-1(x) = x/3 - 4.

The log function is one of these functions. We know that the inverse of a log function is an exponential. So, we know that the inverse of f(x) = log subb(x) is f^-1(y) = b^y. If the base is e and we are dealing with the natural log, then the inverse of f(x) = ln(x) is f^-1(y) = e^y.

Exponentiation and log are inverse functions. Since g(f(x))=x g ( f ( x ) ) = x , f−1(x)=2x f - 1 ( x ) = 2 x is the inverse of f(x)=log2(x) f ( x ) = log 2 ( x ) .

Since g(f(x))=x g ( f ( x ) ) = x , f−1(x)=−x2+5 f - 1 ( x ) = - x 2 + 5 is the inverse of f(x)=−2x+10 f ( x ) = - 2 x + 10 .

The exponential function is its own slope function: the slope of e-to-the-x is e-to-the-x. The inverse of ex is ln x, which is loge x, the natural logarithm of x.
