y is a variable, while f (x) means "the value that f maps x to"; the equation y=f (x) could be read as "y equals the value that f maps x to" or more succinctly as "f maps x to y". 1. [deleted] • 5 yr. ago. On the graph of a function, y and f (x) are very much the same thing. Every point on the graph of f (x) has coordinates: In this *improvised* video, I show that if is a function such that f(x+y) = f(x)f(y) and f'(0) exists, then f must either be e^(cx) or the zero function.

For instance, if f (x) = 5x + 1, then the slope is just 5 everywhere, so f' (x) = 5. Then f'' (x) is the slope of a horizontal line--which is 0. So f'' (x) = 0.

The logic of the previous example extends to finding the potential function for any conservative vector field in ℝ^2.What is the difference between f (x) and y? There is no difference between "f (x)" and "y". The notation "f (x)" means exactly the same thing as "y". You can even label the y-axis on your graphs with "f (x)", if you feel like it.

Trong các mệnh đề sau, tìm mệnh đề đúng:The question is probably hoping you'll write f ′ ( y) = f ′ ( 0) f ( y) which follows from the functional equation. However, the question is entirely wrong since, as you note, f ′ ( 0) = 3 implies f ( 5) = e 15 and could well claim f ′ ( 5) = 3 e 15. This also follows from the givens (as does any other answer). – Milo Brandt.
