Question

given f(x) = 3x-1, find f(x)-f(1) / (x-1)

Answer 1

is the equation written like this?
(3x-1)-1 / ( 3x-1 ) -1 ?

Answer 2

I think you want to write it like this :)
(3x-1)-1 / x - 1

The bottom x should only be the argument of the function :D

Answer 3

Actually, it is written as \[\frac{ 3x - 1 - (3(1) - 1) }{ x - 1 }\]

Answer 4

what do you mean by the only agrument in the function?

Answer 5

Oh f(1) ah sorry about that D:

Answer 6

Saying, f(x) = 3x -1, right?

So f(1) = 3(1) - 1.
Basically you replace the x to 1.

Answer 7

Get it?

Answer 8

oops, i overlooked the fact that the denom didn't have an f. thanks!

Answer 9

No problem.
