Graphing Linear Functions
What about doing the same thing as in the previous section but only with the linear function plotted: (f(x) = -x + 2) Consequently, we create a table of values by selecting some random numbers x=0 and x = 1. Now, substitute the values and pass each as an argument to the expression y = -x + 2 to compute the y values.
X |
Y |
---|---|
0 |
-0 + 2 = 2 |
1 |
-1 + 2 = 1 |
Thus, two points on the line are (0, 2) and (1, 1). If we plot them on a graph and join them by a straight line (extending the line on both sides), we get its graph as shown in the previous section.
Graphing Function
Graphing Function is the process of illustrating the graph (the curve) for the function that corresponds to it. Plotting simple functions like linear, quadratic, cubic, et al. examples doesn’t pose a challenge; depicting functions of a more complex nature like rational, logarithmic, and others requires some skill and some mathematical knowledge to understand them correctly.
In this part, you will be introduced to the joining path of the graphing function, where, in addition to its role as a hunting ground for space in the different fields of mathematics, its application in economics and engineering.
