Answer:
a. Decay
b. 0.5
c. 4
Explanation:
If we have a function of the form

then
a = intital amount
b = growth / decay rate factor
x = time interval
If b > 1; then the equation is modelling growth. If b < 0, then the equation is modelling decay.
Now in our case, we have

Here we see that
inital amount = a = 4
b = 1/ 2 < 0, meaning the function is modeling decay
decay factor = b = 1/2
Therefore, the answers are
a. Decay
b. 0.5
c. 4
ANSWER
The function that the given graph corresponds to is

EXPLANATION
The given graph in the attachment has x-intercepts at

These are the solutions of the polynomial function represented by the given graph.
We can write all these solutions as factors to obtain,

The product of all these factors gives us the function whose graph was drawn.
This implies that,

Therefore the correct answer is option C.
