Is the data set approximately periodic? if so, what are its period and amplitude 1. not periodic
2. periodic with a period of 6 and an amplitude of about 12.5
3. periodic with a period of 6 and an amplitude of about 25
4. periodic with a period of 12 and an amplitude of about 12.5

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.  

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
