solve the problem using excel only please

solve it using excel (b) A researcher had collected data on the forces exerted on the wires in a prosthetic limb during a controlled movement. Unfortunately, the electronics sensor was faulty and some data points were missing from the collected data as shown in Table Q1(b). Determine the value of x that corresponds to f(x)=2.5 by using Lagrange's inverse interpolation with cubic approximation.
