SOLUTION
Given the question in the image, the following are the solution steps to answer the question.
STEP 1: Define the key terms
STEP 2: Match the symbol to the meaning
Hence, the correct meaning matching will be:
200 - 118 = 82
82/200 = 0.41
0.41 x 100 = 41%
The last image is the graph of
In fact, it is an increasing exponential function, and it passes through the points , which reflects the fact that and , which reflects the fact that .
Now, is a child of the parent function we just described. Precisely, it is the result of the transformation
In general, every time you perform a transformation like , you translate the graph horizontall, k units to the left if k is positive, and k units to the right if k in negative.
Since in this case , we have a horizontal translation of 4 units to the right.
So, the correct option is the third one, because:
- The first graph is the parent function translated 4 units to the left
- The second graph is the parent function translated 4 units down
- The third graph is the parent function translated 4 units to the right
- The fourth graph is the parent function
11.25 - 10.5 = 0.75
Knowing that this is the profit she makes with one share, so:
20 * 0.75 = 15
Caroline made $15 profit.
