The question is incomplete. Here is the complete question.
Part A
The value of a collectible toy is increasing exponentially. The two points on the graph show the toy's initial value and its value 3 weeks afterward.
Express the toy's value t, in dollars, as a function of time w in weeks after purchase.
Part B
Write an expression to represent the toy's value 10 days after purchase
Answer and Step-by-step explanation: An exponential function is of the form: 
<u>Part</u> <u>A</u>
Translating to the question, the toy's value as a function of time is

To determine constants a and b, we use points given by graph.
First, (0,5) to find a:

a = 5
Now, (3,10) to determine b:

![b=\sqrt[3]{2}](https://tex.z-dn.net/?f=b%3D%5Csqrt%5B3%5D%7B2%7D)
b = 1.26
The toy's value as a function of time in weeks is 
<u>Part</u> <u>B</u>
Since, the function is in weeks:
1 week = 7 days
w weeks = 10 days

Replacing w:


Expression that represents toy's value after 10 days is

Answer:
2
Step-by-step explanation:
Answer:
m=2/3.
Step-by-step explanation:
the equation for slope is y=mx+b, where m is slope. So, 2/3 is your slope.
We proceed to graph the points and verify which is within the shaded area
so
points B and D are not within the shaded area
point C is not a solution because it is in the limit and the limits are not included
point A is inside the shaded area
therefore
the answer is
the point A
see the attached figure
Answer: The correct option is figure (1).
Explanation:
Reason for correct option:
The figure (1) shows the reflection across the side XY followed by reflection across the side YT.
When we reflect the triangle XYZ across the side XY we get the triangle XYT as shown in below figure.
After that we reflect the triangle XYT across the side YT and we get the triangle PYT.
Therefore, only figure 1 shows the triangle pairs can be mapped to each other using two reflections.
Reason for incorrect options:
The figure (2) shows the rotation of 180 degree along the point y.
The figure (3) shows the reflection across the side XY followed by the translation.
The figure (4) shows the reflection, followed by rotation , followed by translation.
