What are the real zeros of f(x) = x4 - 7x2 + 12? A. x = 3 and x = 4 only
B. V3 and x = 2 only
C. r= -3.x = 3, x = 4, and x = -4
D. x= -13.x = 3.x =
x = -2 and x = 2

go on the tube you might find some information there

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.

i dont know what you want me to answer for this but im guessing 2: 11?
