Find all the values of \(x\)
at which the following expression attains nonnegative value.
\[
x^{2} + x - 12
\]
\(x\in \left (-\infty ;-4\right ] \cup \left [ 3;\infty \right )\)
\(x\in \left [ -3;4\right ] \)
\(x\in \left [ -4;3\right ] \)
\(x\in \left (-\infty ;-4\right )\cup \left (3;\infty \right )\)
\(x\in \left (-\infty ;-3\right ] \cup \left [ 4;\infty \right )\)
