Question

Which is a counterexample that disproves the conjecture?



For all real numbers n, 2n ≥ 1.









A.

n = 0








B.

n = 0.5








C.

n = –1








D.

n = 3

Answer 1

-1 because 2(-1) >/ 1 is a false statement

Answer 2

Oh thank you :)

Answer 3

2n ≥ 1

if n is zero
the equation becomes

2(0) ≥ 1

0 ≥ 1 which is also a false statement
