If you shift the quadratic parent function F (x) = x^2 down 9 units, what is the equation of the new function

f (x) = x² - 9

Step-by-step explanation:

given a function f (x) then f (x) + c translates f (x) vertically by c units

• If c > 0 then translate c units vertically up

• If c < 0 then translate c units vertically down

here f (x) is translated 9 units down, hence new function is

f (x) = x² - 9
