Answer:
equation of new function is

Explanation:
If you shift the quadratic parent function, F(x) = x^2, down 9 units.
Parent function is f(x)= x^2
IF we shift any function 'a' units down then
f(x) becomes f(x) - a
for shifting down subtract 'a' units from the parent function
If you shift the quadratic parent function, f(x) = x^2, down 9 units
then f(x) becomes f(x)-9
So equation of new function is
