Answer 1

$\qquad\qquad\huge\underline{{\sf Answer}}♨$

The required equation is :

$\qquad \bf \dashrightarrow \:y =a \cos(bx) + k$

Now, let's find the required values :

• period (p) = 6

[distance between any successive Crest or trough]

• a = - 4 (flipped)

• b = 2π/p = 2π/6 = π/3

• k = -2

Distance of starting position from origin = k

Now, plug in the values ~

$\qquad \bf \dashrightarrow \: - 4 \cos( \frac{\pi}{3} x) - 2$
