Answer 1

Объяснение:

нет пересечения с осью х

Answer 2

To find the range of the function Y = cos^2(x) + 2, we need to determine the possible values of Y as x varies over its domain. The cosine function is bound between -1 and 1, and when squared, it remains non-negative.

Let's break down the steps to find the range:

Step 1: Find the range of cos^2(x). Since cos^2(x) is always non-negative, its range is [0, 1].

Step 2: Add 2 to the range of cos^2(x). Adding 2 to the range [0, 1], we get [2, 3].

So, the range of the function Y = cos^2(x) + 2 is [2, 3]. The function can take any value between 2 and 3 (inclusive) as x varies over its domain.
