Step-by-step explanation:
Technically, yes, we can define it as a rational function (in a very trivial sense). A rational function is simply the ratio of any two polynomials:
R(x)=P(x)Q(x)
Where P(x) and Q(x) are any two polynomials. In your case we could let:
y=P(x)=5x3–2x+1
And let:
Q(x)=1
For Q(x), you have to remember that constants are polynomials (of degree zero). In this case the constant is just “1”.
P(x) ( your “y” ) divided by 1 is just your polynomial. In a trivial sense this
