Use appropriate Lagrange interpolating polynomials of degrees one, two, and three to approximate each of the following:

a. f (0.43) if f (0) = 1, f (0.25) = 1.64872, f (0.5) = 2.71828, f (0.75) = 4.48169

b. f (0) if f (−0.5) = 1.93750, f (−0.25) = 1.33203, f (0.25) = 0.800781, f (0.5) = 0.687500

c. f (0.18) if f (0.1) = −0.29004986, f (0.2) = −0.56079734, f (0.3) = −0.81401972, f (0.4) = −1.0526302

d. f (0.25) if f (−1) = 0.86199480, f (−0.5) = 0.95802009, f (0) = 1.0986123, f (0.5) = 1.2943767
