Question

F(x) = -×-3
find f(-4)​

Answer 1

Hey there!

Original function: f(x)=-x-3

Substituting -4: f(-4)=4-3

Simplify: f(-4)=1

Let me know if this helps :)

Answer 2

F(x) = -x - 3

F(-4)

Replace x with -4 and solve:

F(-4) = -(-4) -3

-(-4) = positive 4

So you have 4-3

4-3 = 1

F(-4) = 1
