Hi there!

I believe your answer is:
[tex]f(-3)=-43[/tex]
»»————- ★ ————-««
Here’s why:
⸻⸻⸻⸻
[tex]f(x)=-x^2+7x-3\\------------\\f(-3) = -(-3)^2+7(-3)-13\\\\\rightarrow f(-3) = -9 -21-13\\\\\rightarrow f(-3) = -30 - 13\\\\\rightarrow \boxed{f(-3)=-43}[/tex]
⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.
