Answer 1

Hi there!

I believe your answer is:

`f(-3)=-43`

»»————-　★　————-««

Here’s why:

⸻⸻⸻⸻

`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}`

⸻⸻⸻⸻

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