reflection of
over the y axis we get 
Step-by-step explanation:
We need to find the reflection of f(x)=sqrt x over the y axis
So, reflection over y- axis
If the function f(x) is transformed over y-axis then the new function g(x) will be 
So, finding reflection of
over the y axis we get:

So, reflection of
over the y axis we get

Answer:
-4x +3
Step-by-step explanation:
Given the functions f(x) = -2x + 3 and g(x) = 2x We are to find the composite function (f*g(x))
(f*g(x)) = f(g(x))
f(g(x)) = f(2x)
f(2x) = -2(2x) + 3
f(2x) = -4x +3
Hence f(g(x)) = -4x +3
