A Population is modelled by f(x) = 6x^(3/2) + 8x^-3 + 7x where x is the number of years since the population was introduced in the area
What is the instantaneous rate of change at x = 7 years?
df/dx = 9x^(1/2) - 24x^-4
so plug in x=7
What is the instantaneous rate of change at x = 7 years?
so plug in x=7
