Let f(x) = 3x^5/3 and g(x) = -2x^5/3. Find (f + g)(x) and (f - g)(x)
and state the domain of each. Then evaluate (f + g)(-8) and (f - g)(-8).

The physical fitness of an athlete is often measured by how much oxygen the athlete takes in (which is recorded in milliliters per kilogram, ml/kg). the mean maximum oxygen uptake for elite athletes has been found to be 60 with a standard deviation of 7.2. assume that the distribution is approximately normal.
