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

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
