Which expressions are polynomials?

select each correct answer.

y^2−y√3+4

2x^4−y

6 + w

z + 1

what is the degree of the polynomial 3xy^2z−2z^5+2/3y2^z^4 ?

2

4

5

6

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
