👉 In mathematics, a "larithmic" is a function that has an inverse function. This means that for every input value, there's exactly one output value that corresponds to it. For example, consider the function f(x) = 3x^2 - 5x + 7. If we want to find out what x would be if y equals f(x), we can set up an equation and solve for x: y = 3x^2 - 5x +
