\(f(x) = x^2 + 5x +3\)
--> \(f(-4) = (-4)^2 + 5(-4) + 3\)
--> f(-4) = 16 - 20 + 3
--> f(-4) = -1

Option C

Given that \(f(x)=x^2+5x+3\) and we need to find the value of f(-4)

To find f(-4) we need to compare what is inside the bracket () in f(-4) and f(x)

=> We need to substitute x with -4 in \(f(x)=x^2+5x+3\) to get the value of f(-4)

=> \(f(-4)=(-4)^2 + 5*-4 + 3\) = 16 -20 + 3 = -1

So, Answer will be C
Hope it helps!
