Question

What is the equation of the midline of the function f(x) = 5.6sin (2.6x - 4.2) - 9.1?

Answer 1

Answer:

$f(x) = -9.1$

Step-by-step explanation:

The midline is set on $f(x) = -9.1$, when the sine function is equal to zero, eliminating the effect from amplitude. The midline is a horizontal line. Hence, the equation of the midline is:

$f(x) = -9.1$
