What is a binomial, a trinominal, and a polynomial? give examples of each.

Bionomial has 2 terms
trinomial has 3 terms
polynomial has more than 1 terms, it has a countable number of terms, the exponents of the placeholders have to be whole numbers

so bionimal could be x+2 or x³-2
trinomal could be x²+2x-3

polynomail could be all of the above, example
2x²-3x³+24x⁴-4+x

Where’s the graph too show me?
