Use the second derivative test to find the location of all local extrema in the interval (-1, 10) for the function given below.
f(x) = 5x^3/3 - 35x^2/2 + 50x
If there is more than one local maxima or local minima, write each value of x separated by a comma. If a local maxima or local minima does not occur on the function, enter ∅ in the appropriate box. Answer should be exact.
