Question

Is c) true or false? If true, explain why. If false, provide a counterexample

Determine if each of the following statements is true or false. If it's true, explain why. If it's
false explain why not, or simply give an example demonstrating why it's false. (A correct
choice of "T/F" with no explanation will not receive any credit.)
(a) If T : R³ → R³ is linear and det(Ar) = -7, then the volume of the parallelepiped spanned
by the columns of AT is 3.
(b) Let T, S : R" → R" be linear. If T, S are both non-invertible, then To S is non-invertible.
TY – 2z
x – 2y + 3z
(c) The transformation T : R³ → R² given by T
is linear.
