$$ f(x)=2x+3 $$ In this function, $$$ x $$$ is the input variable, and the formula $$$ 2x+3 $$$ describes how the output depends on the input. If you plug in a specific value for $$$ x $$$, you can calculate the corresponding value of $$$ f(x) $$$. For example, if $$$ x=5 $$$, then $$$ f(5)=2\cdot5+3=13 $$$. Graphical Representation
Graph your problem using the following steps: Type in your equation like y=2x+1. (If you have a second equation use a semicolon like y=2x+1 ; y=x+3) Press Calculate it to graph!
Check by graphing a third ordered pair that is a solution of the equation and verify that it lies on the line. Example 1 . Graph the equation y = 2x - 6. Solution We first select any two values of x to find the associated values of y. We will use 1 and 4 for x. If x = 1, y = 2(1) - 6 = -4 if x = 4, y = 2(4) - 6 = 2
