Think & Click: Domain of Trigonometric Functions
Now, you try. Complete the Think & Click activity by looking at each problem below, thinking about it, and then clicking on the question to reveal the solution.
Find the domain and range of y = 2cos(x).
The domain is All Real Numbers.
Since the amplitude of the equation is 2 the range is -2 ≤ y ≤ 2.
Find the domain and range of y = tan(x) + 2.
The domain is All Real Numbers except x = 90° + n180°.
The range is All Real Numbers.
