Question

does f(x) mean y?

Answer 1

Yes, in most cases, the two are the same

Answer 2

ex: y = x+5 is the same as f(x) = x+5

The second is more formal notation to represent a function

Answer 3

if you're talking about xy axes

Answer 4

but lol they're usually same. i just want to be complex

Answer 5

Essentially, it should be backward, though, because we simply write it in point notation as:
\[
(x,y)
\]When it should be:
\[
(x, f(x))
\]

Answer 6

so when it says f(6) you want to find the x value that y=6?

Answer 7

f(6) is the value of y when x is 6

Answer 8

no, f(6) means find f(x) when x = 6

Answer 9

Ex: If f(x) = x+5, then


f(x) = x+5

f(6) = 6+5

f(6) = 11

Answer 10

so the f(6) is -3?
