For 50 points
for the function f(x)=-4 sqrt x-1 find the inverse function
a) f^-1(x)=-(x+1)^2/16, x< _-1
b) f^-1(x)=(x+1)^2/16 , x> _-1
c) f^-1(x)=(x+1)^2/16
d)f^-1(x)=(x+1)^2/16, x< _-1
only answer if you really know, . im really struggling with my class and need some if someone could walk me through this that would mean the world to me.

Which sum or difference identity would you use to verify that cos (180° - ∅) = -cos ∅? a. sin (α -β) = sin α cos β – cos α sin β b. cos (α -β) = cos α cos β – sin α sin β c. cos (α -β) = cos α cos β + sin α sin β d. sin (α + β) = sin α cos β + cos α sin β

The cross-sectional areas of a right triangular prism and a right cylinder are congruent. the right triangular prism has a height of 6 units, and the right cylinder has a height of 6 units. which conclusion can be made from the given information? the volume of the triangular prism is half the volume of the cylinder. the volume of the triangular prism is twice the volume of the cylinder. the volume of the triangular prism is equal to the volume of the cylinder. the volume of the triangular prism is not equal to the volume of the cylinder.
