Question

We can define a one-to-one correspondence between the elements of Pn and Rn by

p(x) = a1 + a2x + a3x2 + … + anxn-  (a1, …, an)T = a

Show that if p  a and q  b, then

(a) αp  αa for any scalarα.

(b) p + q  a + b

[In general, two vector spaces are said to be isomorphic if their elements can be put into a one-to-one correspondence that is preserved under scalar multiplication and addition as in (a) and (b).]
