Question 8 • CMS 2026-2027 NC Math 1 CREDIT RECOVERY
Rewrite the function as f(x) = −(x + 2)² + 6. Its graph opens downward and has a maximum at (−2, 6), so it increases for x < −2 and decreases for x > −2. Therefore, B is true and the range is y ≤ 6, making D true. The y-intercept is f(0) = 2, which is positive, so E is true.
