Deduce from the graph of f(x) = x³+4x² - 10 that this function has a unique real zero a. To compute a use the following fixed point iterations: given x(0), define x(+1) such that (k+1) = 2(x(k))³ + 4(x(k))² + 10 3(x(k))² +8x(k) and analyze its convergence to a. k>0 Deduce from the graph of f(x) = x³+4x² - 10 that this function has a unique real zero a.
