Question

what is the domain and range of the combined function : y=0.95^x/cosx?

Answer 1

well the only domain restriction is when cos(x) = 0
-> x not equal 0 or pi

Answer 2

oops i was thinking sin,
it should be x ne pi/2, and 3pi/2

Answer 3

how do we figure this out?
:S

Answer 4

i believe the range is All Real Numbers, as the function approaches +- infinity at npi +pi/2

Answer 5

and y cannot equal to 0

Answer 6

oh right, yes because .95^x can never be zero
