Question

What is the equation of the midline for the function f(x) ? f(x)=3cos(x)−2.5

Answer 1

Y= -2.5
the midline is basically the line where the distance is the same to the line from the max and the min 

Answer 2

Answer:

the equation for the mid line is y = -2.5

Step-by-step explanation:

The given equation is

$f(x)=3cos(x)-2.5$

On comparing this equation with $f(x)=Acos(Bx+C)+D$

A = 3

B = 1

C = 0

D = -2.5

The mid line for the equation is

y = D

Substituting the value of D

y = -2.5

Thus, the equation for the mid line is y = -2.5
