Question

Find the inverse function:
f(x)=2tan (10x - 3)
Explain please!

Answer 1

You just have to isolate x in terms of f(x)

Answer 2

But how o;

Answer 3

It says the answer is f^-1(x)= 1/10 [tan^-1 (x/2) +3]

Answer 4

Remember that, for example, arcsen(x) is the same as x = sen(y). Of course it's not as simple as this, but consider using its image and domain to help you out..

Answer 5

Aye I got it, thanks (:

Answer 6

Good job.
