Question

X _> 15
x < 10
find interval notation
ASAP PLEASE HELP

Answer 1

• x≥15
• x<10

So

15≤x<10

Interval notation

• [15,10)

Another way

• (-oo,10)U[15,oo)

10 is not included so open bracket

Answer 2

• x ≥ 15, interval notation x ∈ [15, +∞)
• x < 10, interval notation x ∈ (-∞, 10)

Combined together:

• x ∈ (-∞, 10) ∪ [15, +∞)
