Question

How do you prove polynomials?

Answer 1

Step-by-step explanation:

Answers

f(x)=x is continuous everywhere.

If f(x) and g(x) are continuous in D then f(x)g(x) in continuous on D.

Using 2 and 1 show that xn is continuous for every n∈N.

If f(x) and g(x) are continuous on D then f(x)+g(x) is continous on D.

Now use 3 and 4.
