# Example 2

Use a graph to approximate the solution set for the following system of equations. Find

*f(x)*–*g(x)*for your estimates.*f(x)*= 2*x**g(x*) =*x*+ 21. Graph

*f(x)*=*2x*and*g(x)*=*x*+ 2 on the same coordinate axes. 2. Approximate the values for x where*f(x)*=*g(x)*. 3. Evaluate*f(x)*= 2*x*and g*(x)*= x + 2 for*x*= 2. 4. Find the difference in the*y*-values for the equations. This applet is provided by Walch Education as supplemental material for their mathematics programs.
