Best ResponseYou've already chosen the best response.0Well, similar to your last one. F(x) is the normal format. So, in this case, X = 4. Go along the X line until you reach 4. Then, go up until you hit the line. This, is where your Y line is, and your answer.

Best ResponseYou've already chosen the best response.0Remember, a function gives us what's called a "dependent variable" from an"independent variable". If x is 4, it doesn't mean y will be 4. So f(x) does not equal x. f(4) is not necessarily 4. f(4) will be the y coordinate (4,y)

Best ResponseYou've already chosen the best response.0As monkiwi said. Go to the value of x on the graph. What is the y value at that point?

Best ResponseYou've already chosen the best response.0No, it isn't 4. Look at where the points intersect.

Best ResponseYou've already chosen the best response.2we are given f(4) where x = 4.... go to where x = 4 it's like ... (4, y) who is the y in here?

Best ResponseYou've already chosen the best response.0Remember, your answer can only include somewhere that's actually a point on the graph (in this case the infinite points contained in the line)

Best ResponseYou've already chosen the best response.2fineeeeeeeeeeeee F(x) > F(5) implies that x = 5. just find where x = 5 in your chart and you will have y

Best ResponseYou've already chosen the best response.0im sorry.. Im really trying here. you said the 5. and on the chart it has a 2 by it..

Best ResponseYou've already chosen the best response.2I said f(x) was the standard notation of a function . If we have something like f(5).. then .. I said x = 5 because f(x) > f(5) implies that x = 5. on the x chart LOOK UP 5
