Let the functions defined in Column I (1+2x) , tan xhave domain `(-pi/2, pi/2)` and range `(-oo, oo)`

Text Solution

Verified by Experts

The correct Answer is:
`A to q; B to r`
`y=1+2x` is linear function, therefore it is one-one and its range is `(-pi+1,pi+1).` Therefore (1 + 2x) is one-one but not onto so `(A) to (q)`. Again, see the figure.

It is clear from the graph that y = tan x is one-one and onto, therefore `(B) to (r).`
