Question

Q find range of
.. Y= 9-(2tanx - 1)^2​

Answer 1

Answer:

ANSWER

Now the domain of sin−1(x) is [−1,1]

Hence the domain of the above function is [−1,1] since the domain of tan(x) is (−∞,∞) and the rest is a linear function.

Hence

Domain is [−1,1]

Now

f(1)=2π+24π+1+4+1

=π+6.

f(−1)=2−π−24π+1−4+1

=−π−2

Hence

p+q

=π+6+(−π−2)

=6−2

=4
