Assessment: JAMB UTME - Mathematics - 2016 Subject: General Mathematics

Question 1 Report

From the diagram above, find the required roots/region of x.

Answer Details
The required roots/region of x is: - -1 ≤ x ≤ 4 The diagram shows a closed circle at -1 and an open circle at 4, indicating that -1 and 4 are included and excluded from the solution set, respectively. This means that any value of x that is greater than or equal to -1 and less than or equal to 4 is a solution to the inequality. Therefore, the required region of x is the interval between -1 and 4, including -1 and excluding 4.
