| September 10, 2021 | education
The scope of the function will be:
D (x) = R – any real number (the whole number axis);
The function range will be:
E (y) = [-1,3], because:
The range of values of the sinx function:
-1 ≤ sinx ≤ 1;
-2 ≤ 2sinx ≤ 2;
-1 ≤ 1 + 2sinx ≤ 3.
Answer: D (x) = R; E (y) = [-1.3].
