❀
$\underline{ \underline{ \text{Solution}}} :$

~Plug the value of y at first :

➾
$\sf{ {-4}^(2) + 5 * (-4 )+ 1}$

~ Evaluate the power : 4²

➾
$\sf{16 + 5 * (-4 )+ 1}$

Follow the BODMAS { Bracket , Of , Division , Multiplication , Addition and Subtraction } rule :

~Multiply -5 and 4

➾
$\sf{16 + (-20)+ 1}$

~ Multiply the signs : ( + ) and ( - ) :

➾
$\sf{16 - 20 + 1}$

~Add the numbers : 16 and 1

➾
$\sf{17-20}$

~ Subtract 20 from 17

➾
$\sf{-3}$

$\pink{ \boxed{ \boxed{ \tt{⟿ \: Our \: final \: answer : -3}}}}$
