sketch the graph n find the domain and range of y? y(t)=modulus of (2-t) help me?
|dw:1353063606939:dw|domain are all the values of t so if we say t=x y(x)=|(2-x)| so now domain is all values of x range is all values of y |x|=x |-x|=x so based on this we know (2-x) is always positive so now we draw the graph of y=2-x and |2-x| |dw:1353063538238:dw| when you draw the graph of |2-x| you know that all values will be positive so this means your graph is reflected
note:to draw the graph I subbed in values of x this should help you with your question
