Given this function: f ( x )=−2cos(4 πx ) Find the following:

Period = Equation of the mideline:

Maximum = Minimum =

Period =½

Equation of midline, y=0

Maximum =2

Minimum=-2

Step-by-step explanation:

The given function is

The period is given by:

The equation of the midline is y=0 since there is no vertical shift

The amplitude of this function is 2 so the range is -2≤y≤2.

Hence the maximum value is 2 and minimum value is -2

yes

step-by-step explanation:

they have to be opposite and reciprocal of eachother.

answer: no

step-by-step explanation: because the big angle will spread away the 2 side that it is on and make the opposite side even longer.
