Answer 1

$\boxed{ \frak{ \huge \: f \bigg(x \bigg) = \bigg(x - 3 \bigg) \bigg(x + 5 \bigg)}} \ \: \Large \Rightarrow \\ \Large \Rightarrow \: \it \: f \bigg( - 3 \bigg) = \bigg( - 3 - 3 \bigg) \bigg( - 3 + 5 \bigg) = \bigg( - 6 \bigg) \times 2 = - 12 ; \\ \boxed{ \underline{ \frak{ \Huge otvet : \boxed{\underline{ \frak{ \Huge - 12}}}}}} \huge \: .$
