WitrynaIn other words, The logarithm of a number ywith respect to a base bis the exponent to which we have to raise bto obtain y. We can write this definition as x = logby ---> bx= y and we say that xis the logarithm of ywith base bif and only if bto the power xequals y. Witryna27 mar 2024 · By the definition of a logarithm, it is the inverse of an exponent. Therefore, a logarithmic function is the inverse of an exponential function. Recall what it means to be an inverse of a function. When two inverses are composed, they equal x. Therefore, if f(x) = bx and g(x) = logbx, then: f ∘ g = blogbx = x and g ∘ f = logbbx = x top rated pillow top mattress cover https://axiomwm.com
