To determine the number of integers in the range of the function f(x) = 3sinx + 2โ3cosx + 3, we can analyze the properties of the sine and cosine functions.
The range of the sine function is [-1, 1], while the range of the cosine function is also [-1, 1]. This implies that the maximum range of the sum of the sine and cosine functions, 3sinx + 2โ3cosx, will be [-3โ3, 3โ3].
Adding a constant term of 3 to this range will shift the range upwards by 3 units. Therefore, the range of the given function f(x) = 3sinx + 2โ3cosx + 3 is [3 - 3โ3, 3 + 3โ3].
To determine the number of integers in this range, we need to find the number of integers between the two values 3 - 3โ3 and 3 + 3โ3.
Since the square root of 3 (โ3) is an irrational number, the expression 3 - 3โ3 is also an irrational number. On the other hand, the expression 3 + 3โ3 is also an irrational number.
Hence, there are no integers in the given range.
