Answer:
Exponential Decay
Its end behavior on the left is as follows as x approaches negative infinity y approaches positive infinity. Its end behavior on the right is as follows as x approaches positive infinity y approaches negative infinity.
Step-by-step explanation:
We can graph the function by graphing two points when x=0 and x=1.
x=0 has
x=1 has y=
This function starts with higher output values and decreases over time. This is Exponential Decay. Its end behavior on the left is as follows as x approaches negative infinity y approaches positive infinity. Its end behavior on the right is as follows as x approaches positive infinity y approaches negative infinity.
To find our solution, we first write the equation in the following form:
In this formula a represents the slope, therefore:
Because the line passes through the point P(5, -7), we can fill in the coordinates of this point in the formula and we get the following:
Now, add up 1 to both sides and we get
So the formula will be:
Bringing x to the other sides gives us:
Finally we multiply by 5 to get our standard form (and therefore our final answer):
Hence, the answer is D.
