g(x) = x/2
It depends on whether fx denotes frequency times variable value or the probability generating function for the variable x.
If it were written in a book of some sort, fx or f(x) is read aloud as "f or x". "f" is a function of some variable, "x". By function it means something happens to x e.g. x2 or 3x+4.
That is the quotient rule and your function is.... f(x) = X^2/x+2 = (x+2)*2x-x^2*1/(x+2)^2 = 2x^2+4x-x^2/(x+2)^2 = x^2 + 4x/(x+2)^2

[fx] is a function of x, it usually used in graphs.
g(x) = x/2
You need to clarify the function AND provide an interval.
5x lolzz 8)
f(x) = √(2x -3) f(x) = (2x - 3)^(1/2) f'(x) = (1/2)[(2x - 3)^(1/2 - 1)](2) f'(x) = (2x - 3)^(-1/2) f'(x) = 1/[(2x - 3)^(1/2)] f'(x) = 1/√(2x -3)
True
f(x) is the same thing as y= example: f(x)=2x+3 OR y=2x+3
f(x) = (2x^2 + 5x - 12)/(x + 4) as given, is not defined when the denominator is 0 ie when x + 4 = 0 or x = -4. However, 2x^2 + 5x - 12 = (x + 4)*(2x - 3) so that the function can be simplified to (x + 4)*(2x - 3)/(x + 4) = 2x - 3 This has a zero when 2x - 3 = 0 ie 2x = 3 or x = 1.5
Fx represents functions. It is on the Formula Bar and on the Insert Function Button. Clicking on it starts the process of allowing you to enter a function.
