Did I do this right?
The way I did it is found out that f(x)=2/2=1
and that g(x)=2/6=1/3 (Not sure though because the line cuts off before the 2/3 ___
Then I created the problem 1/3=1+k, subtracted 1 and got the answer of k=2/3
I think I might be going places because that most likely isn't the right answer :D

Best ResponseYou've already chosen the best response.0Ok, whenever you add a number to a function like that, you're basically going to shift it up or down by that much. Something called a vertical shift.

Best ResponseYou've already chosen the best response.0So, if you're adding a number 'k' to f(x) to get g(x), count how many vertical spaces they differ by at an xvalue. Like, x = 0 would probably be the easiest. How much do the yvalues differ at x=0?

Best ResponseYou've already chosen the best response.0Not quite. When x = 0, look at what g(x) is first.

Best ResponseYou've already chosen the best response.0from two to six is four spaces

Best ResponseYou've already chosen the best response.0At x=0, g(x) is 2. Are you following me so far?

Best ResponseYou've already chosen the best response.0So, at x=0, you want to see what f(x) is. What do you think f(x) is when x = 2?

Best ResponseYou've already chosen the best response.0When you're trying to find what the yvalue of a function is with a certain x, what you want to do is go to that xvalue and go up or down until you get to the line. So, start at x=0 and y=0, and then go up or down until you get to the line, f(x). Does that help?

Best ResponseYou've already chosen the best response.0So if x=2 then f(x)=2 because at x2 the line is at 2/2

Best ResponseYou've already chosen the best response.0Yes. You're right. If you're going to use x=2, then what is g(x) when x = 2?

Best ResponseYou've already chosen the best response.0Yes, g(x) = 6 when x = 2. So now, you want to take the difference of the two numbers, and that'll be what k is :)

Best ResponseYou've already chosen the best response.0No problem. Also, in this kind of question, you can use any xvalue you want to do it. That's why I said x=0 would be easiest because they yvalues are right there on screen, which would've been 2  (2) = 4. You get it?
