Question

1-The set B={3−2x^2, 6−3x−4x^2, 6x−20+14x^2} is a basis for P2. Find the coordinates of p(x)=45−15x−32x^2 prelative to this basis: 

[p(x)]B=

2-

Let f:ℝ2→ℝf:R2→R be defined by f(⟨x,y⟩)=6x+5yf(⟨x,y⟩)=6x+5y. Is ff a linear transformation?

a.

f(⟨x1,y1⟩+⟨x2,y2⟩)=?

(Enter x1x1 as ??x1, etc.)

f(⟨x1,y1⟩)+f(⟨x2,y2⟩)=  ?
Does f(⟨x1,y1⟩+⟨x2,y2⟩)=f(⟨x1,y1⟩)+f(⟨x2,y2⟩) for all ⟨x1,y1⟩,⟨x2,y2⟩∈ℝ^2?

b-

f(c⟨x,y⟩)=

c(f(⟨x,y⟩))=

Does f(c⟨x,y⟩)=c(f(⟨x,y⟩)) for all c∈ℝ and all ⟨x,y⟩∈ℝ2

c-Is f a linear transformation?
