#### Solution Preview

(1) T(ax^2 + bx + c) = (a + b)x^2 + (b + c)x

(a) Find a basis for Ker T

Ker T is the set of all elements that are mapped into zero.
So a + b = 0 and b + c = 0
So b = -a and c = -b = a
Ker T = { ax^2 - ax + a where a is any real number}

I don't know what format you are using for basis; if you treat the coefficients as a vector, the basis is a single vector (1,-1,1) Only one ...

#### Solution Summary

Linear Transformations, Basis, Kernel, Image, Onto, One-to-one and Matrices are investigated.
