How many integers satisfy (x − 0)(x − 7) < 0?

Answer and explanation

Correct answer: A. 6

  1. Step 1: The product is negative for 0 < x < 7. Step 2. The integers strictly between 0 and 7 number 6. Answer: 6. Why not the others: 7 is what you get if you include one endpoint. 8 is what you get if you include both endpoints. 5 is what you get if you drop one value.
