The graph has a positive slope. by definition: a function is strictly increasing on an interval, if when x1 < x2, then f (x1) < f (x2). if the function notation is bothering you, this definition can also be thought of as stating x1 < x2 implies y1 < y2. as the x 's get larger, the y 's get larger.

Refresh you memory regarding intercepts, positive negative regions. and increasing decreasing interval features of function graphs. intercepts are the locations (points) where the graph crosses (or touches) either the x axis or y axis. • to find the y intercept, set x = 0, and solve for y. Real values and intervals. a function is defined as a real function if both the domain and the range are sets of real numbers. many of the functions you have likely encountered before are real functions, and many of these functions have domain = r. consider, for example, the function y = 3x. a section of the graph of this function is shown below.
