D
Step-by-step explanation:
The formula we need to solve this is:
Where
is the distance from one focus to the vertex
is the second distance from another focus to same vertex
<u>Note:</u> Here, vertex point is the point on top. The common point from which the RED and BLUE line meets the 2 foci
is half the length of the major axis (which is 9 here since total major axis is given as 18)
<em>Now we can plug into the equation and solve:</em>

<em>D is the correct answer.</em>
ANSWER
EXPLANATION
A basic sine curve has equation in the form:
Where 'a' is the amplitude.
In this case a=2 because the amplitude is 2.
For a transformed sine function, the general equation is:
where a=2 is still the amplitude
This is also a sine function with an amplitude of 2.
