Please solve Exercise 1.4.10 with detailed explanations

Exercise 1.4.9 (Challenging): A number x is algebraic if x is a root of a polynomial with integer coefficients,
in other words, anx" +an_1x²-1 +...+a₁x+ag=0 where all an € Z.
a) Show that there are only countably many algebraic numbers.
b) Show that there exist non-algebraic (transcendental) numbers (follow in the footsteps of Cantor, use the
uncountability of R).
Hint: Feel free to use the fact that a polynomial of degree n has at most n real roots.
Exercise 1.4.10 (Challenging): Let F be the set of all functions f: R→ R. Prove |R|< |F| using Cantor's
Theorem 0.3.34.*
