Question

If f (x ) = -4x – 11, what is f (5)?

Answer 1

-31

Explanation:

Answer 2

We are given with a function f(x) = - 4x - 11 , and we need to find f(5) . For which , we just have to put x = 5 in f(x) . So , by putting x = 5 , we have

`{:\implies \quad \sf f(5)=-(4* 5)-11}`

`{:\implies \quad \sf f(5)=-20-11}`

`{:\implies \quad \bf \therefore \quad \underline{\underline{f(5)=-31}}}`
