Question

If the graph of f(x) = x2 is shifted up 9 units, then what would be the equation of the new graph?

Answer 1

\[f(x)=x^2\] ?

Answer 2

\[f(x)=x ^{2}+9\]

Answer 3

Reason like this, what happens at x=0? f(0)=0^2

Answer 4

@Noliec
you mean if x=0 then it could be x=9?

Answer 5

You want the curve to be 9 at f(0) because you're moving it up 9 units.
This leaves the equation f(0)=9 --> f(x)=x^2+9

Answer 6

yes that's right.

Answer 7

Noliec is right.
