The inverse function of is
The function is given as:
Rewrite as;
Swap the positions of x and y
Multiply through by -2
Square both sides
4x^2 = y + 3
Subtract 3 from both sides
y = 4x^2 - 3
Express as an inverse function
Hence, the inverse function of is

Hmm
remember
can translate to 
so
can translate to 
divide both sides by 3
use calculator, if you can't use change of base formula to do it
so
evaluate using base 10 on your calculator
0.560869=x
remember
