If the point (lambda, -lambda) lies inside the circle x² + y² - 4x + 2y - 8 = 0, find the number of integers in the range of lambda.
- 1
- 2
- 3
- 4
Correct answer: 4
Solution
Substituting the point into the circle equation gives a quadratic inequality in lambda. Solve for the range of lambda and count the integers.
