Which is the inverse of the function f(x) = x^2 − 4?

f(x) = x^2 - 4

Replace f(x) with y

y = x^2 - 4

Switch x and y.

x = y^2 - 4

Solve for y.

Add 4 to both sides.

x + 4 = y^2

√ both sides.

√(x + 4) = y

Switch sides, and replace y with f^-1(x)

f^-1(x) = √(x + 4)

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
