**Question:**

Which of the following is (are) a basis of \( P_n(\mathbb{R}) \), the space of polynomials with real coefficients of degree at most \( n \)? (Choose all that apply)

- [ ] \(\{x^n\}\)

- [ ] \(\{1, x, x^2, \ldots, x^n\}\) (degree of \( x \) increases by 1 up to \( n \))

- [ ] \(\{1, x, x^2, \ldots, x^{n-1}\}\) (degree of \( x \) increases by 1 up to \( n-1 \))

- [ ] \(\{x, x^2, \ldots, x^n\}\) (degree of \( x \) increases by 1 up to \( n \))

- [ ] \(\{2, x, 3x^2, \ldots, 2x^{n-1}\}\) (degree of \( x \) increases by 1 up to \( n-1 \))

- [ ] \(\{2x, x^2, x^4, \ldots, 34x^n\}\) (degree of \( x \) increases up to \( n \))

- [ ] \(\{5, 2x, x^2, \ldots, 9x^n\}\) (degree of \( x \) increases by 1 up to \( n \))
