Question

What is the solution set of x < -3 ∩ x ?

the empty set
all numbers except -3 and 5
all real numbers
the numbers between -3 and 5

Answer 1

the empty set {∅}

Explanation:

x ∩ x > 5 is giving us

(-∞, -3) intersecting (5, ∞).

Since those two intervals do not intersect the solution is the empty set
