Expert Solution
Step 1: Define the problem.

straight A equals open square brackets table row 6 0 0 row 0 cell negative 3 end cell 0 row 0 0 cell negative 7 end cell end table close square brackets

Define the linear transformation straight T colon space straight real numbers cubed rightwards arrow straight real numbers cubed by straight T open parentheses straight x with rightwards arrow on top close parentheses equals straight A straight x with rightwards arrow on top

To find the images of straight u with rightwards arrow on top equals open square brackets table row cell negative 3 end cell row cell negative 3 end cell row cell negative 5 end cell end table close square brackets space and space straight v with rightwards arrow on top equals open square brackets table row straight a row straight b row straight c end table close square brackets under straight T.
