Define the set C = x ∈ ℝ | -2 ≤ x < -1 using interval notation.

Here is the definition of set C. Step 1: Understand the set definition. Set C is defined as the set of all x such that x is a real number (R) and x is greater than or equal to -2 and less than -1. C = \x R -2 ≤ x < -1\ Step 2: Express the set using interval notation. The condition -2 ≤ x means that the interval includes the endpoint -2. This is represented by a square bracket [. The condition x < -1 means that the interval does not include the endpoint -1. This is represented by a parenthesis ). Combining these, the interval is from -2 (inclusive) to -1 (exclusive). C = [-2, -1) The set C is the interval from -2 to -1, including -2 but not including -1. C = [-2, -1)
