Question

x + 15 < 0.
itical points for the inequality shown.
select the intervals that must be tested.
□ x < 5
□ x < 3
□ 3 < x < 5
□ x > 3
□ x > 5
done

Explanation:

Step1: Assume the inequality is a quadratic (missing left side, likely \(x^2 - 8x + 15 < 0\), factor: \((x - 3)(x - 5) < 0\)). Critical points at \(x = 3\) and \(x = 5\).

Step2: Intervals divided by critical points: \(x < 3\), \(3 < x < 5\), \(x > 5\). These are the intervals to test.

Answer:

\(x < 3\), \(3 < x < 5\), \(x > 5\) (corresponding checkboxes: \(x < 3\), \(3 < x < 5\), \(x > 5\))
