Find the domain and range of the following:
y=ixi
y= - ixi
y= ixi-6
y=4 - ixi

y=|x|

domain= (-∞,+∞) range= [0,+∞)

y=-|x|

domain= (-∞,+∞) range= [0,-∞)

y=|x|-6

domain=(-∞,+∞) range= [-6,+∞)

y=4-|x|

domain= [-∞,+∞) range= [4,-∞)

binomial distribution

median= 2

range = 7-0 = 7

how to find median?

no. of term=28

median=(28+1)/2=14.5th term

the 14th and 15th term are 2, therefore the median is (2+2)/2 = 2

what is all that apply?
