Answer:  B. -4

Step-by-step explanation:

We are given the function : [tex]f(x)=4x-20[/tex]

To find the value of f(4), we substitute the x equals to 4 in the above function and then simplify it to get the answer.

i.e. At x= 4 , [tex]f(4)=4(4)-20[/tex]

Now, simplify the above expression, we get

[tex]f(4)=16-20=-4[/tex]

Therefore, the correct option is Option (B.) -4 .
