Proof that the continuous image of a compact set is compact
I know that the image of a continuous function is bounded, but I'm having trouble when it comes to prove this for vectorial functions. If somebody could help me with a step-to-step proof, that would be great.
Is the projection function in a normed space continuous?

Prove that $\\sqrt{x}$ is continuous on its domain $[0, \\infty).$
I think you mean a ≠ 0 a≠0. As you have it written now, you still have to show √x x−−√ is continuous on [0, a) [0,a), but you are on the right track. As @user40615 alludes to above, showing the function is …
