Problem: find the value of $x$ that maximizes $$f(x) = \log (-20x + 12\sqrt{x}).$$ if there is no maximum value, write "none".

The value of x is 0.09

Step-by-step explanation:

Here, the given function is,

Differentiating with respect to x,

Again differentiating with respect to x,

For maxima or minima,

At x = 0.09,

f''(x) = negative,

Hence, for x = 0.09, f(x) is maximum.
