Select the correct answer. Roxanne is using successive approximation to solve this equation.
61 + 2 = 1 + 2 - 3
She started from a graph, where she found the solution to be between 1 and 0. Using the lower and upper bounds from the graph, Roxanne started the first iteration of
successive approximation.
