4. The moment exerted on a member that belongs to a bridge is applied and changes throughout the length of the member. To calculate the shear force at any point, we know that we have to take the derivative of the moment. If the moment can be represented as: f(x)=x³-2x+4 on the interval [-2,2] where x is the length of the member. With h=0.25. Use forward, backward, and central difference approximation to calculate the derivative (shear) at point X = 1.5
