In a medical experiment, the number of bacteria is halved every hour. what type of function represents this pattern? a. decreasing linear b. increasing linear c. exponential growth d. exponential decay

D. Exponential decay

Step-by-step explanation:

Let P be the initial number of bacteria,

Given,

The number of bacteria is halved every hour.

So, After x hours the number of bacteria,

Since, it is the type of exponential function ,

Thus, the function represents the given situation is exponential.

Now, there are two types of exponential functions,

(i) Exponential growth : If b > 1

(ii) Exponential decay : if 0 < b < 1,

Now, By comparing,

b = 1/2

Also, 0 < 1/2 < 1

Hence, the function that shows the given situation or pattern is exponential decay.

Option D is correct.

the answer will be b x² +x-1

step-by-step explanation:

a is 8.b is 10.c is 10.5. d is -.5

step-by-step explanation:

just minus the smallest number from the biggest.
