Which represents the reflection of f(x)=sqrt x over the y axis
zloy xaker [14]

reflection of f(x)=\sqrt{x} over the y axis we get g(x)=\sqrt{-x}

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 g(x)= f(-x)

So, finding reflection of f(x)=\sqrt{x} over the y axis we get:

g(x)=\sqrt{-x}

So, reflection of f(x)=\sqrt{x} over the y axis we get g(x)=\sqrt{-x}
