Polynomial-An expression of two or more algebraic terms, which is the sum or difference of the several terms with having different power of the only variable. The difference between the given polynomials is

$=-2x^3y^2 + 9x^2y^3-3xy^4-6x^4y+y^5$

Given-

We have given two function of variable x and y

$(-2x^3y^2 + 4x^2y^3-3xy^4)$

$(6x^4y-5x^2y^3-y^5)$

<h3>Polynomial</h3>

An expression of two or more algebraic terms, which is the sum or difference of the several terms with having different power of the only variable.

Now we have to subtract the two equations to find the difference,

$(-2x^3y^2 + 4x^2y^3-3xy^4)-(6x^4y-5x^2y^3-y^5)$

Multiply the sign into the bracket to open the bracket and further solution,

$=-2x^3y^2 + 4x^2y^3-3xy^4-6x^4y+5x^2y^3+y^5$

Arrange the similar terms in the same groups,

$=-2x^3y^2 + (4x^2y^3+5x^2y)-3xy^4-6x^4y+y^5$ $=-2x^3y^2 + 9x^2y^3-3xy^4-6x^4y+y^5$

Hence, the difference between the given polynomials is $=-2x^3y^2 + 9x^2y^3-3xy^4-6x^4y+y^5$

The total cost, y, for Leah and x friends to go to an amusement park can be modeled by a

Katarina [22]

Answer:

Range of the function is:

{55.25, 100.50, 145.75, 191.00, 236.25, 281.50}

Step-by-step explanation:

Given that:

Seating capacity of the car = 6

Entrance fee per person = $45.25

Parking fee per car = $10

Leah is accompanied by $x$ friends.

So, the total cost can be modeled as the following linear function:

$y=45.25x+10$

Now, the value of $x$ i.e. number of friends going with Leah can be any of the following:

0, 1, 2, 3, 4 or 5 (because maximum capacity of the car is 6).

Leah is also going.

So, total number of people can be 1, 2, 3, 4, 5 or 6.

Therefore, the table of $x, y$ can be:

$\begin{center}\begin{tabular}{ c c}x & y \\ 1 & 55.25 \\ 2 & 100.50 \\ 3 & 145.75 \\ 4 & 191 \\ 5 & 236.5 \\ 6 & 281.50 \\\end{tabular}\end{center}$

Here, the value of $y$ is nothing but the range of the function.

Therefore, the range of the linear function is:

{55.25, 100.50, 145.75, 191.00, 236.25, 281.50}
