How do you write the set in roster form? In set builder notation? D is the set of whole numbers less than 3.

D = {0,1,2}; D = {x | x is a whole number, x < 3}

What is the graph of the inequality? d < 2

D is a number that is less than 2. So choose the graph that shows a black arrow with a white dot, the arrow will point towards the negative numbers.

What is the graph of the inequality? x ≥ -3

X is greater than of equal to -3. So any number including -3 three or above is what the graph is expressing.

What are the solutions of the inequality? Graph the solutions. b - 4 > 4

b > 8
