Q:
# Which of the choices below follow an exponential pattern? Select all that apply.

Accepted Solution

A:

Answer:The choices that follow an exponential pattern is: A. Division of skin cells every half hour. C. [tex]y=4\cdot 3^x[/tex]Step-by-step explanation:We know that an exponential function is one which gradually increases or decreases by a constant rate.A) Division of skin cells every half hour.It will determine a exponential pattern since it could be represented in the form of: [tex]y=ab^x[/tex]where a is the initial amount of skin cells and also the number of skin cells decreases by a constant rate in every half hour.Hence, option: A is correct. B) [tex]y=x^2[/tex]It is not a exponential function.It is a quadratic function.Hence, option: B is incorrect.C) [tex]y=4\cdot 3^x[/tex]It is a exponential function.Since it is represented in the form of: [tex]y=ab^x[/tex]Hence, option: C is correct.D) From the given table we could see that this represent a linear function and not exponential since the values are increasing by a fixed rate i.e. 3Hence, option: d is incorrect.E) You are driving at a constant rate of 55 mph.This situation will represent a linear function or we may say a constant function. Hence, option: e is incorrect.F) [tex]y=2x^3[/tex]It represent a cubic function and not exponential.Hence, option: F is incorrect.
