Given a quadratic function $f(x)=ax^{2}+bx+1(a > 0)$, and a function $F(x)= \begin{cases} f(x)(x > 0) \\ -f(x)(x < 0) \end{cases}$. If $f(-1)=0$, and for any real number $x$ in the domain, $f(x)\geqslant 0$ holds.

1. Find the expression for $F(x)$;
2. When $x\in\[-2,2\]$, $g(x)=f(x)-kx$ is a monotonic function, find the range of values for $k$.
