Answer:
1. x >= 4
2. x /= -4
3. The first one
4. The second one
Explanation:
1. Since the bolded arrow is pointing to numbers greater than 4, we can tell that x is greater than 4. The dot on the number 4 is colored, meaning that four is included, thus x is greater than or equal to 4.
2. Since the bolded areas are on every point on the graph except -4, we can tell that x is every number but -4, thus x is not equal to -4.
3. The sign "<" indicates that x is less than 3. This eliminates the second option. Since there is no equal to sign, the dot isn't colored, thus, the first one.
4. The sign "<=" indicates that x is less than or equal to -1, eliminating the third option. Since it is equal to, the dot should be colored, thus, the second one.
