Question

functions: Power function, Root function, Polynomial function, Rational function, Algebraic function, Exponential function..

1) root5(x)
2) sqrt (4 - x^2)
3) x^8 + x^4
4) (( x^7) + 1 ) / (( x^8) + x )

Answer 1

So whats the question? This looks like a job for the mighty graphing calculator!

Answer 2

Um.. is the question supposed to be asking "Which type of function is each of the following?" If that is the case, then the answers are as follows:

1) Root function
2) Root function
3) Polynomial function
4) Rational function

If more than one answer is allowed per section, you should ammend your origional post. For example all polymomial functions are also rational functions, which in turn are also algebraic functions.
