Question

generalize. write an equation for the midline of the function
y= a cos (b(x-c)) +d

a. y=d
b. y=a

Answer 1

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)

How to determine the midline associated to a sinusoidal function

A sinusoidal function is a trascendental 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 horizontal 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)
