Answer:
Shift of graph of y=x^2 up 9 units.
Option D is correct option.
Step-by-step explanation:
We are given:
[tex]y = x^2[/tex]
We need to describe how the graph of [tex]y = x^2[/tex] can be transformed to the graph of the given equation [tex]y=x^2+9[/tex]
We know the transformation rule:
If f(x) is transformed into f(x)+h, the graph is transformed vertically up h units.
So, In our case:
[tex]y=x^2[/tex] is transformed into [tex]y=x^2+9[/tex]
So, The graph is transformed vertically up 9 units.
Or we can write, shift of graph of y=x^2 up 9 units.
Option D is correct option.
