Question 8 • TX-Pre-Calculus
Use the graph to determine the domain and range of the relation, and whether the relation is a function.
Answer
A
Domain: {x| -10, -8, -6, -4, -2, 0, 2, 4, 6, 8, 10} Range: {y| -6, -5, -1, 1, 3, 4, 5, 7, 8, 10} Yes, the relation is a function.B
Domain: {x| -10 ≤ x ≤ 10} Range: {y| -6 ≤ y ≤ 10} Yes, the relation is a function.C
Domain: {x| -10 ≤ x ≤ 10} Range: {y| -6 ≤ y ≤ 10} No, one y-value is shared by two x-values.D
Domain: {x| -10, -8, -6, -4, -2, 0, 2, 4, 6, 8, 10} Range: {y| -6, -5, -1, 1, 3, 4, 5, 7, 8, 10} No, one y-value is shared by two x-values.
