To determine the inverse of a function, we first write the parent function in terms of y. So, in this part the x would be isolated to one side of the equation. Then, with the new form of the parent function, we switch the x into y and y to x. The new function would be the inverse function. For the given function, we do as follows:

<span> y=-4/x + 1 
y - 1 = -4/x
x ( y - 1 ) = -4
x = -4 / (y -1)

Replacing x into y and y into x,

</span>y = -4 / (x -1)

<span>Therefore, the inverse is y=-a/x-b where a = 4 and b = 1.</span>

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

The required equation is :

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