Will give brainliest! What is the equation for the midline for the function f(x) = 2 + cos x ?

Step-by-step explanation:

A midline of a cosine function is the horizontal center line about which the function oscillates above and below.

Given the function

The function has the range and, therefore a midline with equation

The graph of the function can be obtained by translation the graph of the function wo units up. Hence, the midline will be translated 2 units up too and its equation will be

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1

i would need to see the dot plot : )
