Question

Select the set-builder notation for the set of numbers greater than or equal to 7.

a) z
b) 2 > 7
c) 2 > 7
d) 2 < 7

Answer 1

The set-builder notation for the set of numbers greater than or equal to 7 is x ≥ 7, but none of the options provided in the question correctly represents this notation.

Step-by-step explanation:

The student has been asked to select the set-builder notation for the set of numbers greater than or equal to 7. The correct notation should indicate that any element x of the set satisfies the condition x ≥ 7. None of the provided options a), b), c), or d) correctly represent this notation. They contain typographical errors as they have incorrect variable placeholders or logical statements that do not match the requested condition.

The correct set-builder notation should be expressed as x ≥ 7. This notation reads as "the set of all x such that x is greater than or equal to 7.”
