For functions, the two notations mean the exact same thing, but "f(x)" gives you more flexibility and more information. You used to say "y = 2x + 3; solve for y when x = –1". Now you say "f(x) = 2x + 3; find f(–1)" (pronounced as "f-of-x is 2x plus three; find f-of-negative-one").

Updated: If you are saying (x)=(x^2 - 2)/(x-1) [please update your equation with brackets and powers if this is incorrect] to determine the instantaneous rate of change, we need to calculate the derivative, and then substitute our value of x=2 to obtain the instantantaneous rate of change.

Im having some trouble understanding Big-O estimates. Im using Discrete Mathematics And Its Applications by Rosen 6th Edition. In section 3.2 one of the example problems says to show that f(x) - x^2 + 2x + 1 is O(x^2).

This means we have to find the sign of the function between zeros and apply the definition of absolute value. As you noted, there are zeros at 0 and 2; these are the only two zeros of $x^2-2x$. We can check signs between and outside these points to find that. $x^2-2x>0$ if $x>2$ or $x<0$. $x...
