Answer:
The correct answer is B
Step-by-step explanation:
Let's understand the graph.
A line is drawn starting in 4.5 and involving all numbers greater than 4.5.
But notice that in the starting point the line is drawn with an open circle, this means that the line does not consider 4.5 as part of its domain, this means that 'k' values are greater than 4.5.
Values greater than 4.5 are represented as >4.5, then:
k>4.5, which is option B, because:
k>9/2 = k>4.5
Note: Option A (k≥4.5) means that the line involves 4.5 as part of its domain, which is false as mentioned before.
