Determine whether the linear transformation T is one-to-one and whether it maps as specified

Question 8 (1 point) Determine whether the linear transformation T is one-to-one and whether it maps as specified. Let T be the linear transformation whose standard matrix is A = -2 -9 Determine whether the linear transformation T is one-to-one and whether it maps R3 onto R3. O A) One-to-one; not onto R3 OB) Not one-to-one; onto R3 O C) One-to-one; onto R3 ( D) Not one-to-one; not onto R3
