a) \(h(x) = {1 \over x}\)

b) \(y = {3x^{2} - 2x^{5} + 4}\)

c) \(y = {-4x^{4} - 4x + 3}\)

d) \(y = {x^{1 \over 2} - 7}\)

 

I'm extremely lost... all I can guess is that they're all polynomial functions since they all have a degree?

I found this definition

 

"A polynomial function is a function such as a quadratic, a cubic, a quartic, and so on, involving only non-negative integer powers of x. We can give a general defintion of a polynomial, and define its degree."

 

This is the definition that I thought was right...

By this definition A and D are NOT polynomials

A polynomial function is a term used when there is more than one part to an equation. polynomial, in this case, they all are except A. Becasue D is a binomial and B/C are both trinomials
