The function y = 3x^2 - ln x + 1. The maximum value of the function lies at x = a if x = a is the solution of y' = 0 and y'' is negative for x = a.
y = 3x^2 - ln x + 1
y' = `(6*x^2-1)/x`
y'' = `(6*x^2+1)/x^2`
As x^2 is always positive, the value of y'' is positive for all values of x.
The graph of the given function is:
The given function y = 3x^2 - ln x + 1 does not have a maximum value.
