Question

If f(x) = 6x – 4, what is f(x) when x = 8?

Answer 1

Answer:

f(x) = 44, when x = 8

Step-by-step explanation:

Step 1: Given data  

F(x) = 6x-4

Given Value of   x is 8

To calculate   the value of f(x):

Step 2:  Given f(x) = 6x-4   ……………… (1)

Replace x by 8 and then solve in the way shown in the solution

If x=8, then  

Step 3: Substitute x = 8 in Equation (1) we get

Step 4:  f(8)=(6 x 8)-4

=48-4

=44

Therefore f(8) = 44

Answer 2

Answer:

If x=8 then f(8)=44

Step-by-step explanation:

Given f(x)=6x-4

Substitute x=8 in f(x),we get

f(8) = 6×8-4

= 48-4

= 44

Therefore,

If x=8 then f(8)=44
