Select all equations that could define the function f. A. f(-x) = -1? + 8x - 12
B. f(-x) = x2 - 8x +12
C. (.x) = (x + 2)(x + 6)
D. f(x) = (x – 4)2 + 4
E. f(x) = (x - 4)2 - 4
F. f(x) = (x-2)(x - 6)

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
