Approximate the solutions for system of equations.

Use a table of values to approximate the solutions for the following system of equations: [math]f(x) = 3^x[/math] [math]g(x) = 2x + 1[/math]

[list=1] [*]Create a table of values. [*]In column [math]f(x) - g(x)[/math], look for sign changes. [/list]
