Zorich Mathematical Analysis | Solutions

Exercise 3.1: Prove that the function $f(x) = x^2$ is continuous on $\mathbbR$.

Solution: Let $x$ be a real number and $\epsilon > 0$. We need to show that there exists a rational number $q$ such that $|x - q| < \epsilon$. Since $x$ is a real number, there exists a sequence of rational numbers $q_n$ such that $q_n \to x$ as $n \to \infty$. Therefore, there exists $N$ such that $|x - q_N| < \epsilon$. Let $q = q_N$. Then $|x - q| < \epsilon$, which proves the result. zorich mathematical analysis solutions
