Write the equation for the cosine function that has been compressed vertically by a factor of 2, stretched horizontally by a factor of 4, and shifted down one unit

Step-by-step explanation:

Consider the function f(x) = cos x. Noted below are the points of transformations of the cos function

Considering the points above, we can now write down the "transformed" cosine function's equation:

f(x) =

c.35

step-by-step explanation:

8+13=21

21+8=29

29+6=35
