The domain is the set of all the values that go into a function.

WebSolved Examples. Question 1: Represent y =. x 2. + 4x + 1 using function notation and find the value of y at x = 3. WebThe f is just a way for you to know that when you see f (x) to treat it as a function and not mistakenly treat it as multiplying one variable by the other (it DOES NOT mean f multiplied by x). It does not have to be an f, it can be any symbol and using different symbols such as h (a) helps differentiate one function from another. ( 46 votes) Flag hilux kun26
Evaluating and Solving Functions College Algebra Corequisite
WebWhen we do have a function we use a mathematical shortcut to talk about it. We write output= f(input) o u t p u t = f ( i n p u t) and we can use any letter to represent the function, the input or the output. For example, to indicate that a quantity y y is a function of quantity x, x, we write y = f(x) y = f ( x) and say y y equals f f of x x.
