Use the bisection method with an error tolerance = 0.04 and with the following initial bounds

Question:

Use the bisection method with an error tolerance ϵ = 0.04 and with the following initial bounds to interactively solve (approximately) each of the following problems.
(a) Maximize f(x) = 6x – x2, with x = 0, x-bar = 4.8.
(b) Minimize f(x) = 6x + 7x2 + 4x3 + x4, with x = – 4, = 1,
