Find all the hypercritical values of the function. f(a) = x® – 4x4 – 27x2 The concentration of a drug in the bloodstream C(t) at any time t, in hours, is described by the equation 100t c(t) = 2 + 25 where t = 0 corresponds to the time at which the drug was swallowed. Determine how long it takes the drug to reach its maximum concentration. It will take hours until it reaches its maximum concentration. Suppose a baby...
