Final answer:

The transformation t(x,y,z)=(x,y,z) is linear because it satisfies the properties of linearity.

Step-by-step explanation:

To show that the transformation t−R³ →R², where t(x,y,z)=(x,y,z), is linear, we need to demonstrate that it satisfies the properties of linearity. For a transformation to be linear, it must satisfy two conditions:

  1. t(u + v) = t(u) + t(v), for all vectors u and v
  2. t(cu) = ct(u), for all vectors u and scalar c

Let's use these conditions to prove the linearity of the given transformation:

  1. t(u + v) = (u + v) = (u + v) = (u) + (v) = t(u) + t(v)
  2. t(cu) = (cu) = c(u) = ct(u)

Since the transformation satisfies both conditions, we can conclude that the transformation t(x,y,z)=(x,y,z) is linear.
