Answer:

The correct answer is "Option C".

Step-by-step explanation:

Given:

\bold{ 1) y= -\tan (x- \frac{\pi}{2})}\\\\\bold{ 2) y= \tan (x+ \frac{\pi}{2})}\\\\\bold{ 3) y= -\cot (x- \frac{\pi}{2})}\\\\\bold{ 4) y= \cot (x+ \frac{\pi}{2})}\\\\

solve the above equation:

\Rightarrow 1) \ y= -\tan (x- \frac{\pi}{2})\\\\\Rightarrow \ y= \tan (\frac{\pi}{2}-x)\\\\\Rightarrow \ y= \cot x \ \ \ \ \ \bold{ that \ matchs \ graph \ D}\\\\ \Rightarrow 2) \ y= \tan (x+ \frac{\pi}{2})\\\\\Rightarrow \ y= - \cot x \ \ \ \ \bold{ that \ matchs \ graph \ A}\\\\

\Rightarrow 3) \ y= -\cot (x- \frac{\pi}{2})\\\\\Rightarrow \ y=\cot ( \frac{\pi}{2}-x)\\\\\Rightarrow \ y=\tan  x\ \ \ \ \bold{that \ matchs \ graph \ C}\\\\

\Rightarrow 4) \ y= \cot (x+ \frac{\pi}{2})\\\\\Rightarrow  \ y= \cot (\frac{\pi}{2}+x)\\\\\Rightarrow  \ y= \ -tan x \ \ \ \ \  \bold{ that \ matchs \ graph \ A}

The final answer is "Option C".

Row 3 (x + y)²             1    2   1

Row 4 (x + y)³           1   3    3   1

Row 5 (x + y)⁴         1   4   6   4   1

        ∵

Row n (x + y)ⁿ⁻¹      1 (sum of 2 digits above) 1
