Question

sketch the graph n find the domain and range of y?
y(t)=modulus of (2-t)
help me?

Answer 1

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|



when you draw the graph of |2-x| you know that all values will be positive so this means your graph is reflected
