Q. Which of the following is a solution to the inequality below?−4≤fChoices:(A) f=−11(B) f=−9(C) f=−2(D) f=−6
Understand the inequality: Understand the inequality.The inequality −4≤f means that f can be any number greater than or equal to −4.
Evaluate choices: Evaluate each choice to see if it satisfies the inequality.Start with choice (A) f=−11.Check if −11≥−4.−11≥−4 is not true, so (A) is not a solution.
Check choice (A): Move to choice (B) f=−9.Check if −9 is greater than or equal to −4.−9≥−4 is not true, so (B) is not a solution.
Check choice (B): Evaluate choice (C) f=−2.Check if −2 is greater than or equal to −4.−2≥−4 is true, so (C) is a solution.
Evaluate choice (C): There is no need to check the remaining choices because we have found a solution that satisfies the inequality.
