In this setting, we often describe a function using the rule, y = f(x), and create a graph of that function by plotting the ordered pairs (x,f(x)) on the Cartesian Plane. This graphical representation allows us to use a test to decide whether or not we have the graph of a function: The Vertical Line Test.
Evaluate each function for the given value. 1) f (x) = 4x + 2; Find f (0) 2) f (x) = -2x + 2; Find f (-3) 3) f (x) = 2x; Find f (-9 5) 4) f (x) = -3x; Find f (3 5) 5) f (x) = 3x - 4; Find f (0.2) 6) f (x) = x + 6; Find f (3.8) 7) f (x) = x - 3 - 5; Find f (8) 8) f (x) = -3x - 4; Find f (3) 9) f (x) = x2 + 2x - 4; Find f (-1) 10) f (x) = x2 - 8x ...
Interpreting Function Graphs Algebra Understanding and interpreting graphs can be difficult. Uderstanding the relationship between the x and y-axis is very important. Example: The following graph shows the distance traveled by a school bus based on every morning from 6:30-7am. distance (miles) time (minutes) 0 15 30 10 20 1. What do the flat ...
Algebra Graphing with Coordinates Graphs in two dimensions are very common in algebra and are one of the most common algebra applications in real life. Coordinates The plane of points that can be graphed in 2 dimensions is called the Rectangular Coordinate Plane or the Cartesian
This unit explains how to see whether a given rule describes a valid function, and introduces some of the mathematical terms associated with functions. In order to master the techniques explained here it is vital that you undertake plenty of practice exercises so that they become second nature.
