Question

Given f (x) = -4x - 5, find f ( -4 )

Answer 1

x= -4 therefore
-4 x -4 = 16
16-5=11
Ans=11

Answer 2

Answer: f(-4) = 11

Explanation:

In order to evaluate this function, I am going to plug in -4 for x:

`\sf{f(x)=-4x-5}`

`\sf{f(-4)=-4(-4)-5}`

`\sf{f(-4)=16-5}`

`\sf{f(-4)=11}`

Therefore, f(-4) = 11.
