Answer:
A. horizontal reflection
Step-by-step explanation:
Given:
To identify the type of transformation.
Solution:
On close observation of the functions we find the that sign of has changed in
with other terms being constant.
<em>Thus, the transformation statement can be given as:</em>
As:
The transformation describes horizontal reflection of function across the y-axis.
Thus, is horizontally reflected across y-axis to get
.
The correct answer is Choice A.
This is an example of an exponential equation, so we need the formula
.
The a value is the starting value of 100. The b value must be a decimal lower than 1 because it is decreases.
If you substitute in 8 for x, you will see that the output is about 50 (half of 100).

Answer:
You are clicking on graphs.
However, you should sketch a graph of your function to see what the correct one looks like.
Create a table containing a few values of x and y
I chose x = -4, -2, 0, 2, 4.
Draw your axes
Plot your points
Draw the graph
Your graph should look like the one below.
