What is the range of (f(x)=5-(x+1)2)?

Explanation opens after your attempt
Correct Answer

A. ( \(-\infty,5]\)

Step 1

Concept

Since ((x+1)2\ge 0), (5-(x+1)2\le 5). In exams check the maximum value of a downward parabola.

Step 2

Why this answer is correct

The correct answer is A. ( \(-\infty,5]\). Since ((x+1)2\ge 0), (5-(x+1)2\le 5). In exams check the maximum value of a downward parabola.

Step 3

Exam Tip

क्योंकि ((x+1)2\ge 0), इसलिए (5-(x+1)2\le 5)। परीक्षा में नीचे खुलने वाले परवलय की अधिकतम वैल्यू देखें।
