You set the equation equal to zero and you get -4,2,2 and if u plug this numbers in to get y then you get 0

You have to start by writing everything out

f(x)=(x+4)(x-2)(x-2)(x-2)

now you multiply... let's start with (x+4)(x-2)

x^2-2x+4x-8 ---> x^2+2x-8

now we multiply that by the next set (x^2+2x-8)(x-2)

x^3-2x^2+2x^2-4x-8x+16 ---> x^3-12x+16

and again, we multiply by the next set (x^3-12x+16)(x-2)

x^4-2x^3-12x^2+24x+16x-32 ---> x^4-2x^3-12x^2+40x-32

and that is your final answer

Answer:

Exponential function; $y=120(\frac{1}{2})^x$ .

Step-by-step explanation:

We have been given that a tennis tournament starts with 120 players. During each round of the game, half of the players are eliminated from the tournament.

We can see that the change in number of eliminated players is not constant. The number of players in tournament is decreasing exponentially. Therefore, an exponential function best models the relationship between the number of players in the tournament, y, and the game round, x.

We know that exponential decay function is in form $y=a(b)^x$ , where,
