<u><em>Explanation:</em></u>
<u>The given is:</u>
<u>To find the inverse, follow the below procedures:</u>
<u>1- Convert f(x) to y. </u>
<u>This will give:</u>
<u>2- Swap the x and y variables.</u>
<u>This will give:</u>
<u>3- Solve for y.</u>
<u>This will give:</u>
<u>4- Replace the y in the above step with f⁻¹(x).</u>
<u>This will give us:</u>

Hope this helps :)
Answer:
θ = 2π/3 or 5π/3
Step-by-step explanation:
2 cosθ + 1= 0
when + 1 goes to R H S Side than it becomes negative by transposition method
2 cos = -1
now by dividing by 2 both sides we get
cosθ = -
since cosθ is negative
Cosθ = - cos 60°
it means either cosθ lies in 2nd or third quadrant
θ = π - π/3
or
θ = 2π- π/3
so θ = 2π/3 or 5π/3
