Answer #1

1) (d) bisection divides the interval into half by calculating mid point and evaluating function values on it. hence:
mid-point = -0.75
function value = (-0.75)^3-(-0.75)-11 = -10.6719

2) (d) open methods use gradients to approximate the next guess

3) (c) Newton raphson requires the knowledge of exact derivative

4) (c) As both the methods choose initial bracketing points having opposite sign of function value. Neither bisection or false position can determine the root

5) (c) Newton raphson method can diverge
