Question

If f(x)=cos^(-1)x what is the domain, range, continuity, is it increasing or decreasing, symmetry, boundedness, extrema, asymptotes, and end behavior?

Answer 1

Domain- R-{(2n+1)pi/2} where n is whole no.
Range (-infinity,-1] or [1,ifinity)
continuous - not continous throughout
not bounded I think
asymptoes-(2n+1)pi/2 n is whole number

Answer 2

what about symmetry id it odd or even and the end behavior?

Answer 3

even
