3 Graphically Speaking Objectives A very effective method of representing a function is graphically. The way in which the output quantity changes as the input increases can often be more readily identified in visual form. A graph can also show any trends or patterns in the function situation. 2. Defining Functions Graphically 1. Represent a function verbally, symbolically, numerically, and graphically. 2. Distinguish between a discrete function and a continuous function. 3. Graph a function using technology.
