By direct comparison with the expression described in the statement, we could conclude that the equation for the midline of the function is y = K. (Correct choice: A)
<h3>How to determine the midline associated to a sinusoidal function</h3>
A <em>sinusoidal</em> function is a <em>trascendental</em> formula whose form is described below:
y = A · cos [B · (x + C)] + D (1)
Where:
- y - Dependent variable
- x - Independent variable
- A - Amplitude
- B - Frequency
- C - Phase
- D - Midline height
In addition, a <u><em>horizontal</em></u> line, that is, a line parallel to the x-axis, is:
y = K (2)
By direct comparison with the expression described in the statement, we could conclude that the equation for the midline of the function is y = K. (Correct choice: A)
