Question

1. Which of the following have the same domain and range? I. y = 2x - 1 II. y = -x + 2 III. x = 2 1. II. III. y = x - 1 - 2x + 3y = -5 2x + 3y = 2 (A) I and III only (B) I and II only (C) II and III only (D) I, II and III

Answer 1

The first two equations are lines.

Domain is the set of allowed x values for the function.

Range is the set of allowed y values for the function.
