Calculus/Functions A function is always defined as of a variable which tells us what to replace in the formula for the function. For example, () = + tells us: The function is a function of . To evaluate the function at a certain number, replace the with that number.

Function Notation & Evaluating at Numbers You do exactly the same thing in either case: you plug in –1 for x, multiply by 2, and then add the 3, simplifying to get a final value of +1. But function notation gives you greater flexibility than using just  y  for every formula. Your graphing calculator will list different functions as y1, y2, etc. In textbooks and when writing things out, we use names like f(x), g(x), h(x), s(t) , etc.

What is a Math Function Table? Functions. A function is a rule that applies to a variable. Let's say everybody (except your friend) did poorly on the test, and your teacher decides to use a curve to change all the grades. The rule he uses for the curve is to bump everybody's grade up by 3 points.

Exponential function The input variable x occurs as an exponent – hence the name. A function of the form ƒ (x) = b is also considered an exponential function, and a function of the form ƒ (x) = a · b can be re-written as ƒ (x) = b by the use of logarithms and so is an exponential function.
