A basis of R² is given by B = {(3,4), (-2,-3)}. You are given the B-matrix for the
transformation Tis
[T]B = M =

(a) From lecture, we know the B-matrix can be written as M = P-¹AP. What is
the matrix P (write out the matrix)?
If [w])s = [3]
By inspection, determine [(-5, -7)]B.
Use the appropriate parts of the problem to help you determine how to write
T(-5, -7) as a linear combination of the basis vectors in B. Write out the
linear combination. Computing T(-5, -7) explicitly is optional, but can help
for partial credit and to check if your answer makes sense.
