Which of the following have a frequency factor of b = 1?
a sine function whose period is 21 radians
a sine function whose x-coefficient is 21
a cosine function with no phase shift whose x-coefficient is 1
a sine function whose graph shows 2 cycles from - 41 radians to 0
a sine function whose graph shows 2 cycles from 0 to 21 radians
a cosine function whose graph shows 4 cycles from 0 to 41 radians
a cosine function whose graph shows 1 cycle from 37 radians to 57 radians

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
