Well if its exponential it must be x ^n
Its1. every number/variable that has a power to the zero, its goin to turn out to be just one
<em><u>The expressions that are polynomial are:</u></em>
6 + w

z + 1
<em><u>Solution:</u></em>
A polynomial is an expression with variables and coefficients with the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables
1) 6 + w
Here "w" is a variable, hence it is a polynomial expression

This is a polynomial, since it has variables and coefficients and variable with non negative exponent
3) z + 1
This is also a polynomial with variable "z" and has addition operation

Since it has root so it is not a polynomial
Answer:
Do y²-y¹/x²-x¹. So do 18-4/3-0 in order to get 14/3 and your slope intercept form! Hope this helped
