By evaluating in x = π/3, we conclude that the correct option is C.
<h3>Which is the graphed function?</h3>
By looking at the graph, we can see that the function becomes zero when:
x = π/3
Now, this is really trivial.
Just evaluate the four options in x = π/3, and see which ones become equal to zero, and discard the others.
By doing that, you will see that the only option that becomes zero when evaluated in x = π/3 is option C.
Then we conclude that it is the only option that can be the correct one.

<u>Convert a Repeating Decimal to a Fraction </u>
We need to convert the following decimal to a fraction:
Let's call x to the given number:
The number has two repeating (periodic) decimals, thus we multiply by 100:
Note the decimals continue to repeat exactly like the original number.
Subtracting both expressións, the repeating decimals are simplified:
Operating:
99x=-37
Dividing by 99:
The fraction cannot be simplified, thus:
