Answer:
49/24

Explanation:

First, find the common denominator (24)
Secondly, multiply 2/3 by 8 since 8x3=24
Now you have 16/24 instead of 2/3
Thirdly, multiply 3/4 by 6 since 4x6=24
Now you have 18/24 instead of 3/4
Lastly, multiply 5/8 by 3 since 8x3=24
Now you have 15/24 instead of 5/8
Since you found the common denominator and changed all of the fractions you can add them all together.
16/24 + 18/24 + 15/24 = 49/24

Hope this helps!!!

$f(x) = x^2 +3 \\\\\text{Write f(x) as}~ y = x^2 +3 \\\\\text{Replace x with y and solve for y}\\\\x = y^2+3\\\\\implies y^2 = x-3\\\\\implies y=\pm\sqrt{x-3}\\\\\implies f^{-1}(x) = \pm\sqrt{x-3}\\\\\text{This is the inverse of f(x).}$
