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.

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:

Part A

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 = 1.26

The toy's value as a function of time in weeks is

Part B

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 .

0,0
