ok lemme solve it

y = 2x^2 - 8x + 5 = 2(x-2)^2  -3

solve for x direcftly

y + 3 = 2(x-2)^2

(x-2)^2 = y+3 /2

x-2 = sqrt(\frac{y+3}{2}

x = sqrt(\frac{y+3}{2} +2

g-1 (x) = 2 + sqrt(\frac{x+3}{2} +2

i know its a complicated way of showin....but im new so not dat much experienced....

u found perfect square in  (i)...
use dat 1 2 find de g-1
(i) =2(X-2)2+1....
let g(x)= y
y=2(x-2)2 +1...
(y-1)/2= (x-2)2...
{(y-1)/2}1/2= (x-2)...
[{(y-1)/2}1/2]+2=x...
hence g-1(x)=[{(x-1)/2}1/2]+2...
NOW PUT K VALUE....K=2...
g-1(2)=9/4

i guess it must be -3

its latex

click on the pi symbol

and type in sqrt(watever u want to type)

like this

sqrt(watever u want to type)

@shrey - what guess!, it has to be -3 @vaan - dude, good method,  but check ur complete the square thingy its not +1 its -3
