Respuesta :
we have that
y = 2x² + 2
step 1
exchange the value of x for y and the value of y for x
y = 2x² + 2------> x=2y²+2
step 2
clear y variable
x=2y²+2----> 2y²=x-2----> y²=[(x-2)/2]-----> y=(+/-)√[(x-2)/2]
step 3
the inverse is
f(x)-1=(+/-)√[(x-2)/2]
y = 2x² + 2
step 1
exchange the value of x for y and the value of y for x
