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

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
