Evaluating Piecewise Functions
Given the function

f(x)={5x2+4x<110x221x15x>1\displaystyle {f{{\left({x}\right)}}}={\left\lbrace\begin{array}{cc} -{5}{x}^{{2}}+{4}&{x}<-{1}\\-{10}{x}^{{2}}-{2}&-{1}\leq{x}\leq{1}\\{5}&{x}\gt{1}\end{array}\right.}

Calculate the following values:
f(2)=\displaystyle {f{{\left(-{2}\right)}}}=  
f(1)=\displaystyle {f{{\left({1}\right)}}}=  
f(2)=\displaystyle {f{{\left({2}\right)}}}=
