Question

Whose graph appears to be identical to the given graph

Answer 1

The correct answer is Option A.

Explanation:

Because of the given polt, we know we're looking for a function f(x) such as:

`f(0)=1`

Notice that this is true for options a and d, ruling out options b and c.

Now, we also know that the function we're looking for has a period of:

`6\pi`

This way, we'll know that the correct answer is:

Option A.
