We observe that
the vertex of f(x) is located at the point (0,0)
and
the vertex of g(x) is situated at (0,5)
thus,
(x,y) in f(x) becomes -------> (x,y+5) in g(x)
g(x)---------> f(x)+5
g(x)=x²+5
the answer is
g(x)=x²+5
(10x)^(-3)
= 1/[(10x)^3]
= 1/[10^3 * x^3]
= 1/(1000x^3)
The final result is 1/(1000x^3), and none of the given choices seem correct. (Option C would be correct if it used round brackets.)
Hope this helps~
