Require two initial guesses to begin the algorithm

Use a gradient to approximate the next guess of the root

Are sensitive to the shape of the function

May diverge when approximating the next guess of the root

Exact derivative of the function is required

Mid-point is calculated to determine the root estimate

One initial guess with a perturbation is required to begin the algorithm

Derivative is approximated using a chord

only the bisection, false position and Newton-Raphson methods.

all of the methods: bisection, false position, Newton-Raphson, secant and modified secant.

none of the methods as the function never touches the x axis.

the false position method but not the bisection method.

False position

Bisection

Newton-Raphson

All of the above

a and b are of the same sign

Function values at a and b are of the same sign

Function values at a and b are of opposite signs

a and b are of opposite signs

Two roots will be returned

Bisection method cannot be used with these bounds

This equation has no real roots

A single root will be returned
