Question

Please answer my question

Answer 1

Interval notation uses parenthesis and brackets, while inequality notation uses inequality symbols.

a)

Interval notation: [-4, 8)

Inequality notation: $-4\leq x$

x >= -4, x < 8

---For inequality notation, it can also be written as two separate inequalities. I am not sure what your teacher is looking for, so I will provide both the compound and separate formats.

b)

Interval notation: (-infinity, 7)

Inequality notation: x < 7

c)

Interval notation: (-infinity, -6) U (0, infinity)

Inequality notation: $-6> x \geq 0$

x < -6, x >= 0

Hope this helps!
