Which expressions are polynomial?
y
4x^3+y
2+s

which description is correct for the polynomial 4x^2+3x+5
cubic trinomial
quadratic trinomial

Polynomial means more than 1 term when all like terms are combined
terms are seperated by plus or minus symbols
you can't combine placeholders and numbers

y is 1 term, not poly
4x^3+y is 2 term, poly
2+s is 2 term, poly

answer is 4x^3+y and 2+s

cubic means highest power of the placeholder is 3
quadratic means highest power of placeholder is 2

trinomial means 3 terms

yep, 3 terms

4x^2+3x+5
highest power is 2
quadratic trinomial

I’m pretty sure the slope would be 1 since the x and y values increase by 1
