The function f(x) = g(x), where f(x) = 2x-3 and g(x) = x^2-5. the table shows the process of solving using successive approximations.

F(x) = G(x) so that means 2x-3 = x^2-5 doing the math gives you x^2-2x-2=0, solve that and plug your x values back into the equation and find if both solutions work or if there is an irrational answer

table 3 represents a direct variation function. : )
