Write “a number a plus 7.8 is more than 9” as an inequality.

• a + 7.8 > 9

• a + 7.8 < 9

• a + 7.8 ≤ 9

• a + 7.8 ≥ 9

Find the domain and range of the function represented by the graph.

• The domain is -3 ≤ x ≤ 4, and the range is -1 ≤ y ≤ 4.

• The domain is -3 < x < 4, and the range is -1 < y < 4.

• The domain is -1 < x < 4, and the range is -3 < y < 4.

• The domain is -1 ≤ x ≤ 4, and the range is -3 ≤ y ≤ 4.
