Given the function f(x)=7x2+6x1\displaystyle {f{{\left({x}\right)}}}={7}{x}^{{2}}+{6}{x}-{1}. Calculate the following values:

f(0)=\displaystyle {f{{\left({0}\right)}}}=  
f(2)=\displaystyle {f{{\left({2}\right)}}}=  
f(2)=\displaystyle {f{{\left(-{2}\right)}}}=  
f(x+1)=\displaystyle {f{{\left({x}+{1}\right)}}}=  
f(x)=\displaystyle {f{{\left(-{x}\right)}}}=
