We have the vectors a1 = (-2,5) and a2 = (-3,8) in the vector space R2 and the linear transformation f: R2 -> R2 defined by
f(a1) = 2a1 - a2 and f(a2) = -4a1 + 2a2
I have to find the transformation matrix with respect to the standard basis for R2.
My attempt :
It would be nice if someone could look at it
