How many integer solutions does (-2<x\le 4) have?

Answer and explanation

Correct answer: (6)

The direct answer is option C, 6. The inequality is \(-2<x\le4\). The open sign at -2 means -2 is excluded, while the closed sign at 4 means 4 is included. List the integers greater than -2 and at most 4: \(-1,0,1,2,3,4\). Counting them gives six integers. Option A, 5, misses one valid integer. Option B, 7, counts too many, usually by including -2 incorrectly or adding another number outside the interval. Option C, 6, matches the complete list. Option D, 4, omits two valid values. A number-line picture makes this clear: place an open circle at -2, a closed circle at 4, and count the integer marks between them. The common mistake is to treat an open endpoint as included. Here -2 must not be counted, but 4 must be counted.
