Identify the type of function represented by f(x) = 4•(1/3)^x O A. Decreasing linear
O B. Increasing linear
C. Exponential decay
D. Exponential growth

I need help please!!!

C

Step-by-step explanation:

By looking at the exponent you can immediately tell the function is an exponential one. However, to further determine if it's positive or negative you need to look at the base of the exponent. If the base is above 1 the function is positive, while on the other hand if it is smaller than 1 it is negative. In this case the base is 1/3 which is equal to .33, so this function is an exponential decay.

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
