Evaluating Functions
Given the function f(x)=5x5x+1\displaystyle {f{{\left({x}\right)}}}=\frac{{-{5}{x}-{5}}}{{{x}+{1}}}. Calculate the following values:

Note: Round the answer to two decimal places as needed. 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)}}}=
