Unformatted text preview: 2. Consider the (ordered) bases α = (1 ,x,x 2 ) and β = ( x 2 + 1 ,x, 2 x 2 + x-1). (a) (5 pts) Compute [ L ] α α , the matrix representing L relative basis α . (b) (10 pts) Compute [ L ] β β , the matrix representing L relative basis β . (c) (8 pts) Compute P β α , the matrix changing α-coordinates to β-coordinates. (d) (2 pts) What are the kernel and image of L ? Clearly label which is which. (4) (10 pts) Let P k be real polynomials of degree ≤ k , and L : P 1 → P 2 be integration (without arbitrary constant). For example, L (1) = x . Let α = ( x + 1 ,x-1) and β = ( x 2 + 1 ,x + 1 , 2 x 2-1) be (ordered) bases for P 1 ,P 2 respectively. Find [ L ] β α . 1...
