The distance between the two points is -12
It can be done.
You must take a few steps to set it up, but then you are able to count 7 minutes. The setup makes you be able to time 2 minutes on the 5-minute sandglass and then you do another 5 minutes on the same sandglass.
Setup:
Start both sandglasses at the same time. When the 5-minute sandglass runs out, the 8 minute sandglass has 3 minutes of sand left. At this moment, start the 5 minute sandglass again.
When the 8-minute sandglass finishes the remaining 3 minutes, the 5-minute sandglass has 2 minutes left.
Actual timing of 7 minutes:
Let the 2 minutes pass, and immediately turn over the 5-minute sandglass to count an addition 5 minutes. The last 2 minutes of the 5-minute sandglass plus an additional 5 minutes of the 5-minute sandglass add to 7 minutes.
By applying the definition of <em>exponential</em> function, we find that the function f(x) = 3 · 2ˣ match with the graph of the picture. (Correct choice: A)
<h3>What is the equation behind the exponential curve seen in the graph?</h3>
In this question we have the graph of a <em>exponential</em> function, whose expression have to be found based on the definition of <em>exponential</em> function:
y = a · bˣ (1)
Where:
- a - Initial value of the exponetial function.
- b - Base of the exponential function.
- x - Independent variable
- y - Dependent variable
Now we find the values for a and b:
Initial value (x = 0, y = 3)
3 = a · b⁰
a = 3
Base of the exponential function (x = 1, a = 3, y = 6)
6 = 3 · a
a = 6 / 3
a = 2
By applying the definition of <em>exponential</em> function, we find that the function f(x) = 3 · 2ˣ match with the graph of the picture. (Correct choice: A)
