So in my linear class we are reveiwing some things befor we start working out of the book and i got this as a practice ?. I am confused on what is being asked and how to start off.
Let P5 be the set of all polynomials of degree 5 or less. Let p(x) be an element of P5 with p'(x) its derivitive. define function f as follows.
f: P5[tex]\rightarrow[/tex]P5
f(p(x))=xp'(x) + 1
a. find f(5x5+4x2+3)
b. is f 1 to 1 and explain
c. is f onto and explain
