Identify a true statement on the function
\(f(x) = 1 + 2x^{2} -\frac{1}
{4}x^{4}\).
The global maximum of \(f\)
on \(\mathbb{R}\) is
at \(x = 2\) a
\(x = -2\).
The function \(f\) has
a global minimum on \(\mathbb{R}\).
The function \(f\) has a
local maximum at \(x = 0\).
The function \(f\)
has neither local minimum nor maximum.
