You can see that the function is graphed for every number x that is greater than or equal to zero.
So we write that the domain is

.
<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:
Step-by-step explanation:
Cost of one ticket = $ 5
Cost of 'n' tickets = 5 * n = 5n
