Use a graph to approximate the solutions for the following system of equations. Find [math]f(x) - g(x)[/math] for your estimates. [math]f(x) = 2^x[/math] [math]g(x) = x + 2[/math]
[list=1] [*]Graph [math] f(x) = 2^x [/math] and [math]g(x) = x + 2[/math] on the same coordinate plane. [*]Approximate the values for [i]x[/i] where [math]f(x) = g(x)[/math]. [*]Evaluate [math] f(x) = 2^x[/math] and [math] g(x) = x + 2[/math] for [math] x = 2[/math]. [*]Find the difference in the [i]y[/i]-values for the equations. [*]Evaluate [math]f(x) = 2^x[/math] and [math]g(x) = x + 2[/math] for [math]x = -2[/math]. [*]Find the difference in the [i]y[/i]-values for the equations.
