Does this chamber represent a function ? why or why not?

No, this does not represent a function. A function is defined: each x value can correspond to only 1 y value. However, the 3 in the x column is corresponding to two y values: 4 and 3. Therefore, this isn't a function.

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.

step-by-step explanation:

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.
