Question

In function notation, f(x) takes the place of what?

Answer 1

Answer:

The f (x) notation is another way of representing the y-value in a function, y = f (x). ... Note: The notation f : X → Y tells us that the function's name is "f " and its ordered pairs are formed by an element x from the set X, and by an element y from the set Y.

Step-by-step explanation:

Answer 2

Answer:The f(x) takes the place of the y-axis

The F in f(x) stands for the functions name.

The X in f(x) stands for the ordered pair.

The f(x) is the same as Y= 2x - 1

Step-by-step: f(x) = 2x - 1

F(x) =  F(13)

F(13) = 2*13-1=26-1=25

2*13=26  26-1=25

so the answer to f(x)=2x-1 would be 25 because the x in f(x) is a 13 and you would multiply the 2 by 13 and that would equal 26 then you would minus 1 and the answer would be 25

Explanation:

Function notation is the way a function is written. It is meant to be a precise way of giving information about the function without a rather lengthy written explanation.The f (x) notation is another way of representing the y-value in a function, y = f (x).  The y-axis may even be labeled as the f (x) axis, when graphing.  Ordered pairs may be written as (x, f (x)), instead of (x, y).

I hope this is correct and if it is I hope it helps.
