Question 210120
find the inverse of f(x)=2 sqrt(x+3)
---
Interchange x and y then solve for "y":
x = 2sqrt(y+3)
sqrt(y+3) = x/2
y+3 = (x^2/4)
y = (x^2/4)-3
---
That is the inverse but it is not listed as one of your options.

a) f^-1(x)=(x-3/2)^2 
b)f^-1(x)= (x+3/2)^2 
c)f^-1(x)= 1/2 sqrt(x-3) 
d)f^-1(x)= 1/2 sqrt(x+3)
