Question

Which expression is equivalent to |b|>2 ?

Answer 1

Answer:

b < –2 or b > 2

Step-by-step explanation:

The given expresion is

$|b| \: > \: 2$

By the definition of absolute value function.

|x|=x, if x>0

|x|=-x, if x<0

This implies that:

$b \: > \: 2 \: or \: - b \: > \: 2$

Divide the second inequality by -2 and reverse the sign

$b \: > \: 2 \: or \: b \: < \: - 2$

Option B is correct
