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 = 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 .
Check the picture below.
let's notice that the angle -150° has a reference angle of 30°, so any trigonometric function for either angle will be the same value, however, let's recall that the sine or y-coordinate is negative on the III Quadrant, so sin(-150°) is the same as sin(30°) BUT negative, -sin(30°).
Answer:
The graph is attached below.
Step-by-step explanation:
First, we want to isolate the "x" term from the equation. We do this by subtracting "2" from both sides.
This gives us x is greater than -1. So, we can graph:
