To Find:

Value of f(x) when x = -3

Step-by-step explanation:

$\sf \implies f(x) = {x}^{2} - 2x \\ \\ \sf \implies f( - 3) = {( - 3)}^{2} - 2 ( - 3) \\ \\ \sf \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 3 - ( - 6) \\ \\ \sf \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: =3 + 6 \\ \\ \sf \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: =9$
