Q. Which is the set of integers greater than −4 and less than or equal to 1?Choices:(A){−4,0,1}(B){−4,−3,−2,−1,0,1}(C){−3,−2,−1,0,1}(D){0,1}
Identify Inequality Signs: Let's first identify the inequality signs. We need to find the set of integers that are greater than −4 and less than or equal to 1. The inequality signs we are looking for are: > for greater than and ≤ for less than or equal to.
Translate to Set Notation: Now, let's translate the inequalities into set notation. The set notation for integers greater than −4 and less than or equal to 1 is: \{x \,|\, -4 < x \leq 1\}.
List Integers in Range: Next, we need to list the integers that satisfy the inequality -4 < x \leq 1. Remember that integers are whole numbers, so we need to list the whole numbers in this range.The integers greater than −4 are −3,−2,−1,0,1,2,3, ... and so on.However, we are only interested in those less than or equal to 1.
Match with Given Choices: Listing the integers that satisfy both conditions, we get: −3, −2, −1, 0, 1. These are the integers that are greater than −4 and less than or equal to 1.
Match with Given Choices: Listing the integers that satisfy both conditions, we get: −3,−2,−1,0,1. These are the integers that are greater than −4 and less than or equal to 1. Now, let's match our set of integers with the given choices. (A) {−4,0,1} includes −4, which is not greater than −4. (B) {−4,−3,−2,−1,0,1} also includes −4, which is not greater than −4. (C) {−3,−2,−1,0,1} does not include −4 and includes all integers from −41 to 1, which satisfies our condition. (D) −43 does not include all integers greater than −4 and less than or equal to 1.
