Graph Of A Function Lessons Tes Basic functions. in this section we graph seven basic functions that will be used throughout this course. each function is graphed by plotting points. remember that f(x) = y and thus f(x) and y can be used interchangeably. any function of the form f(x) = c, where c is any real number, is called a constant function.

Graphing The Basic Functions Figure 2.4.1. the graph of a constant function is a horizontal line. the domain consists of all real numbers ℝ and the range consists of the single value {c}. we next define the identity function44 f(x) = x. evaluating any value for x will result in that same value. for example, f(0) = 0 and f(2) = 2. Graphing basic functions like linear functions and quadratic functions is easy. the basic idea of graphing functions is. identifying the shape if possible. for example, if it is a linear function of the form f(x) = ax b, then its graph would be a line; if it is a quadratic function of the form f(x) = ax 2 bx c, then its a parabola. The basic absolute value function changes direction at the origin, so this graph has been shifted to the right 3 units and down 2 units from the basic toolkit function. see figure \(\pageindex{6}\). figure \(\pageindex{6}\): graph of two transformations for an absolute function at \((3, 2)\).
