Which function is the inverse of f(x)= x^2 -16 if the domain of f(x) is x>0 OA. 5-11%) = VI + 16
OB. 9-17) = vi + 4
Oc. f-11x) = Vo – 16
OD. -18) = vo – 4

Factor. 8x2y2 – 4x2y – 12xy 4(8x2y2 – x – 12xy) 4(2xy – 4x2y – 12xy) 4x2y2(2xy – xy –3) 4xy(2xy – x – 3)

All per-unit concepts rely on ratios, meaning, to provide a type of measurement
