1. a. Find the slope of the curve f(x) = (4x-3) /(x2 - 4) at x=0.
b. Using part a) above, find the linearization L(x) at x = 0 and use it to approximate f(0.1).
c. Find the differential df.
2. A sphere was measured and its radius was found to be 45 centimeters with a possible error of no more that 0.01 centimeters. What is the maximum possible error in the volume if we use this value of the radius?
