Question

Find a basis for the vector space { f ∈P3 | f (0) = 0}. 

Expert Solution
Step 1

Given- The vector space is  fP3  f0=0

To find- The basis for the given vector space.

Step 2

Explanation- 

Let

fx=ax3+bx2+cx+d

Now,

f0=0a03+b02+c0+d=0d=0

So,

The vector space is:

fP3  f0=0=ax3+bx2+cx=ax3+bx2+cx

So,

The basis is x3 , x2 , x.
