Homework Statement
Find the kernel and range of the following linear mapping.
b) The mapping T from [itex]P^{R} to P^{R}_{2}[/itex] defined by
[itex]T(p(x)) = p(2) + p(1)x + p(0)x^{2}[/itex]
The Attempt at a Solution
I'm not sure how to go about this one. Normally I would use the formula T(x) = A * v but in this case I don't know how to find A or v. Would be great if someone could point me in the right direction.
Thanks in advanced.
