Answer:
D.  g(x)  =  (x+ 4)² + 6
Step-by-step explanation:
Here, the given function is f(x)  = x²
Now,if a graph  x² is translated by (h,k) where:
h = Translation  done towards RIGHT
k = Translation  done towards UP
Then the translated equation is given as:
y =    (x-h)² + k    .... (1)
Now here, the graph is translated 6 UNITS UP  and 4 UNITS LEFT.
⇒  h =  - 4 and k = 6
Substituting the value of h, k in (1) , we get:
g(x) =  (x-(-4))² + 6  =  (x+ 4)² + 6  
⇒ g(x)  =  (x+ 4)² + 6
Hence,  the equation of the translated function, g(x) is g(x)  =  (x+ 4)² + 6.
