Question

How do you find the domain of `F(x)=2x^3-x^2+3`?

Answer 1

Domain: `(-oo,+oo)`

Explanation:

`F(x) = 2x^3-x^2+3`

`F(x)` is defined `forall x in RR`

Hence, the domain of `F(x)` is `(-oo,+oo)`

This may be inferred from the graph of `F(x)` below.

graph{2x^3-x^2+3 [-6.36, 6.126, -1.445, 4.8]}
