Evaluating Functions
Given the function f(x)=8x2+7x+4\displaystyle {f{{\left({x}\right)}}}={8}{x}^{{2}}+{7}{x}+{4}. Calculate the following values:

If the output does not exist, enter DNE\displaystyle {D}{N}{E}
f(2)=\displaystyle {f{{\left(-{2}\right)}}}=
f(1)=\displaystyle {f{{\left(-{1}\right)}}}=
f(0)=\displaystyle {f{{\left({0}\right)}}}=
f(1)=\displaystyle {f{{\left({1}\right)}}}=
f(2)=\displaystyle {f{{\left({2}\right)}}}=
