Consider the following function. f(x) = x/32 (note that 5 is under the square root in the denominator) Find the largest interval(s) on which f is increasing. Consider the following function. f(x)=5x x/32 e (note that 5 is under the square root in the denominator) Find the largest interval(s) on which f is concave up. Problem #4(a): Problem #4(b): Consider the following function. f(x) = 9e x - 8x, 0 x5 == (a) Find the largest value of f(x) on the given interval. (b) Find the smallest value of f(x) on the given interval.

If the trend continues, approximately how many people will eventually contract the disease? Round your answer to the nearest person. Problem #6: Find the critical number of f(x) = x7 Inx. (Note: 0 is not a critical number because it is not in the domain of f.) Problem #6: Enter your answer symbolically, as in these examples
