(3) Identify the domain and range of the relation, and determine whether the relation is a function {(-7, -12), (-3, -5), (1, 16), (8, 18)} (A) Domain: {-7, -3, 1, 8); Range: {-12, -5, 16, 18); Not a function (B) Domain: {-12, -5, 16, 18); Range: {-7, -3, 1, 8); Not a function (C) Domain: {-12, -5, 16, 18}; Range: {-7, -3, 1, 8); Function (D) Domain: {-7, -3, 1, 8); Range: {-12, -5, 16, 18); Function (4) Find the indicated function and write its domain in interval notation. p( x) = x² + 2x, q(x) = √(1-x), (q/p)(x) = ? (A) (q/p)x = √(1-x)/(x² + 2x); (-∞, -2) U (-2, 0) U (0, ∞) (B) (q/p)x = √(1-x)/(x² + 2x); (-∞, -2) U (-2, 0] U (0, 1] (C) (q/p)x = √(1-x)/(x² + 2x); (-∞, -2) U (-2, 0) U (0, 1] (D) (q/p)x = √(1-x)/(x² + 2x); (-∞, -2) U (-2, 0) U (0, ∞)
