The parent function f(x)= square root of (x) is stretched horizontally by a factor of 4, reflected across the y-axis, and translated left 2 units. Write the square-root function g.

-
f(x)=rt(x)

Stretch horizontally to get...

g_1(x)=rt(4x)

Reflect to get...

g_2(x)=-rt(4x)

And finally, translate it left by two units to get...

g(x)=-rt(4x+2)
