(Chapter 1: Review) 1.13 PART F: GRAPHS OF FUNCTIONS The graph of f , or the graph of y = fx () , in the standard xy -plane consists of all points [representing ordered pairs] of the form x , , where x is in the domain of f . In a sense: Graph of f = x , x ± Dom f {} . Here, as we typically assume, … x is the independent variable , because it is the input variable. y is the dependent variable , because it is the output variable. Its value (the function value ) typically “depends” on the value of the input x . Technical Note : Even for a constant function f where, say, = 3 , we refer to y as the dependent variable, even though (informally speaking) the value of
