Consider the following table giving mass as a function of
Age, a (days) Mass, M (g)
0.5 ..................... 0.125
1.0 ..................... 1.000
1.5 ..................... 3.375
2.0 ..................... 8.000
The data follow the equation M(a) = a3. Estimate each of the following using the tangent line approximation and the secant line approximation. Which approximation is closer to the exact answer? Which method would be best if you did not know the formula for M(a)?
M(1.25)
