Keywords:
Function, exponential, neperian logarithm, properties, argument of the function
For this case we have a function\(f (x)\)given by exponential and neperian logarithm, in which, by means of properties of exponential and neperian logarithm we must find the argument of the function. We have: \(f (x) = e ^ {ln (7x)}\)
By properties of exponential and neperian logarithm we have:
\(e ^ {ln (x)} = x\)
So, we have that:\(f (x) = e ^ {ln (7x)} = 7x\)
Then, the argument of the given function is: \(7x\)
Answer:
The value of \(f (x) = e ^ {ln (7x)} is 7x\)
