What does F 2 X mean?

f2 (x) means f squared, i.e., [f(x)]2 . 6. AcellOfllSpades • 6 yr. ago.

Is F 2 x the same as F x?

1 Expert Answer Jake, the answer is No! f(f(x)) means replace each x in f(x) by the entire function f(x).

Is there a difference between the meaning of F x and FX?

Usually f and f(x) are used interchangeably. But rigorously they should be used in the following way. The single letter f denotes the function, i.e. the machine in which you can plug in a value and get another value out.

How do you change from FX to GX?

Given a function f(x), a new function g(x)=f(x)+k, g ( x ) = f ( x ) + k , where k is a constant, is a vertical shift of the function f(x). All the output values change by k units. If k is positive, the graph will shift up.

What does FX X 2 mean?

So f(x) shows us the function is called “f”, and “x” goes in. And we usually see what a function does with the input: f(x) = x2 shows us that function “f” takes “x” and squares it. Example: with f(x) = x2: an input of 4.

What is 2 X mean?

When you see the notation 2X, where X is a set, we’re also considering 2 as a set, in fact 2={0,1}. So 2X is the collection of all functions mapping X to {0,1}. It’s been stated in a comment that 2X is the power set of X, that is, the collection of all subsets of X.

What is the difference between F of X and X?

‘f’ is just the name of the function, ‘x’ is just the function’s input and ‘y’ is just the function’s output.

What does function f mean?

It is often written as “f(x)” where x is the input value. Example: f(x) = x/2 (“f of x equals x divided by 2”) It is a function because each input “x” has a single output “x/2”: • f(2) = 1.

What does F(2X) mean?

Also what does f (2x) mean in words? thanks 2*f (x) means two multiplied by the function f. f (2x) means the function at 2x; or the value of the function evaluated at 2x. Giving a name f to a function for the function using independant variable x will be named as f (x), to be read, “the function f of x”.

What does f(x) = (x)?

The ‘ (x)’ is somewhat meaningless to the notation, and serves only to remind you what the independent variable is. Say you have the function f (x)=x. If you prefer variables like t, or s, for example the result of the function is the same.

What does 2f(x) mean on a graph?

Again, 2f (x) would be 2x 2, not x 2. For y = x 2, the vertex is at (0, 0), so doubling the y-value has no effect. The graph of y = 2x 2 will also have (0, 0) as its vertex. All other points will be twice as far away from the x-axis as those on the graph of y = x 2.

What is the value of y = 2*f(x)?

Assuming that you have the graph of y = f (x), a new function y = 2*f (x) has y values that are exactly twice the value of those on the graph of y = f (x). This can be thought of as an expansion of the graph of f away from the x-axis to get y = 2*f (x).
