Write the equation for the inverse of the function y=cos^-1(x-pi)

we are given

Since, we have to find inverse function

step-1:

Set y=f(x)

It is already there

step-2:

Switch x and y

step-3: Solve for y

We can take cos on both sides

we can simplify it

now, we can solve for y

..............Answer

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
