Since you're going towards the left you can say that your answer is getting "more" negative for the first coordinate. As such you want your answer to be less negative than -21, also the second coordinate seems to be getting "less negative" as such anything less than -9 should not be an option. Lastly the difference between the two points for the first coordinates is 5, more specifically you are subtracting 5 to the first coordinate and for the second coordinate you are adding 3. Following this patter we say that the answer is
and so, the answer is B (-26,-5)
and so, the answer is B (-26,-5)

Step-by-step explanation:
<u>The Cosine Function</u>
The graph of a cosine function is a sinusoid that starts at its maximum value of 1 at x=0 and takes x=2π radians to complete a full cycle. The function of the parent cosine function is:
Both the amplitude A and the angular frequency w of a cosine can be modeled by the function
The graph of the cosine function shown in the figure has an amplitude of A=3 and it completes a full cycle at x=π/2, thus:
Thus:
Therefore, the equation of the sinusoid is:
