Question

F(x) = -x^2 + 7x – 13
Find f(-3)

Answer 1

To find f(-3), substitute -3 for x in f(x) = -x^2 + 7x - 13.

Step-by-step explanation:

A mathematical expression is a combination of numbers, variables, and operations (such as addition, subtraction, multiplication, and division) that represents a mathematical relationship. It can be as simple as "2 + 3" or more complex, involving variables and functions.

To find f(-3), we need to substitute -3 for x in the given function f(x) = -x^2 + 7x - 13. This gives us:

f(-3) = -(-3)^2 + 7(-3) - 13

= -9 + (-21) - 13

= -9 - 21 - 13

= -43

Therefore, f(-3) = -43.

Answer 2

f(-3)=-25

Step-by-step explanation:

Putx=-3

f(-3)=-(-3)^2+7(-3)-13

f(-3)=9-21-13

f(-3)=-25
