Use your schools library, the Internet, or some other reference source to find real-life applications of approximations of functions.

The population P (in millions) of Texas from 2001 through 2014 can be approximated by the model P=20.913e0.0184t, where t represents the year, with t=1 corresponding to 2001. According to this model, when will the population reach 32 million?

Sketch the graph of fx=5e0.17x.

Why do we restrict the domain of the function f(x)=x2 to find the function's inverse?

The graph of fx=1/x is a .

The number of bacteria in a refrigerated food product is given by N(T)=23T256T+1,3T33 ,where T is the temperature of the food. When the food is removed from the refrigerator, the temperature is given by T(t)=5t+1.5 , where t is the time in hours. a. Find the composite function N(T(t)) . b. Find the time (round to two decimal places) when the bacteria count reaches 6,752.

The population of a pad of bottlenose dolphins ismodeled by the function A(t)=8(1.17)t, where tisgiven in years. To the nearest whole number, whatwill the pod population be after 3 years?
