Question

F(x)=-3x²+2x-5
What is f(-1)?​

Answer 1

Answer: f (-1) = 9

Explanation:

You just have to substitute -1 for x

f (-1) = -3 (-1)^2 + 2 (-1) - 5

f (-1) = 3^2 + -2 - 5

f (-1) = 9 - 7

f (-1) = 2

I think I'm correct so I hope this helped!

Answer 2

`f(-1)=-3.(-1)^(2) +2.(-1)-5\\=\\-3.1+(-2)-5\\-3+(-2)-5\\-5-5=-10`
