<span>0.000099 in scientific notation
=
9.9 x 10^-5</span>
Answer:
A.
exponential
Step-by-step explanation:
Exponential is best suited here because life span gradually increases from b to a over the years continuously. Whenever there is a continuous steady increase, exponential function is more suitable.
Logrithamic function will not suit because rate of change of log is 1/x and if x population is very large this will be almost equal to 0 which is not correct.
But exponential say a^x rate of increase= a^x log a and when a is small this will represent a slow steady state of increase.
Step function will not suit as step functions are discontinuous at every integral value, but the population function is a continuous function.
Absolute value function is suitable only for functions symmetrical about a particular value of x or y
But here there is no symmetry but steady increase. Hence exponential is the best suitable graph.
