3. which of the following are the roots of the quadratic function below?
select all that apply.
f(x) = x2 - 144
12
2

x = ± 12

Step-by-step explanation:

Given

f(x) = x² - 144

To find the roots set f(x) = 0, that is

x² - 144 = 0 ( add 144 to both sides )

x² = 144 ( take the square root of both sides )

x = ± = ± 12

ha!
