6. Then number of infected individuals in a population can be modeled with the following function: 20 I(t) = 10 − √ t, where t is measured in days. (a) Using linear approximation, estimate the number of in- fected individuals at time t = 18. You should linearize around the point t = 16. (b) Starting at t = 16, use linear approximation to estimate the number of newly infected individuals over the next 0.5 days.

For the function f(x,y)=x^3+y^3-3xy-ln(r)-e^c+t You find that at the point (2,4) the value of the function is 50 f(2,4)=50 Suppose you were to estimate the values of the following points: A = （1.997，4.003） B = （2.004，3.996） C = （2.000，3.997） D = （1.996，4.000） At which point(s),would you expect (without calculation) the value of the function be larger than f (2,4) = 50? Also provide a quick (one line) explanation of why you would expect the value to be larger than 50.
