State whether the function is a polynomial function or not. If it is, give its degree. If it is not, tell why not.

f(x) = 16x⁴ + 9x³ + 6

option

1. Yes; degree 4

2. No; the last term has no variable

3. Yes; degree 7

4. Yes; degree 8

State whether the function is a polynomial function or not. If it is, give its degree. If it is not, tell why not.

f(x) = x^4/3 - x³ + 10

option 

1. Yes; degree 4/3

2.Yes; degree 3

3. Yes; degree 4

4. No; x is raised to non-integer 4/3 power
