Step-by-step explanation:
An open circle indicates that x cannot equal that value
A closed circle indicates that x can equal that value.
(i)
An open circle at x = - 1 and arrow pointing right
x > - 1
(ii)
An open circle at x = - 1.5 and arrow pointing right
x > - 1.5
(iii)
A closed circle at x = 4 and arrow pointing left
x ≤ 4
(iv)
A closed circle at 0.5 and arrow pointing left
