A cosine function is a reflection of its parent function over the x-axis. The amplitude of the function is 2, the vertical shift is 11 units down, and the period of the function is . The graph of the function does not show a phase shift.

What is the equation of the cosine function described?

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

your answer is the frist one

hop i

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
