Which polynomial function has zeros at 2, −4, and 1?
y = (x + 2)(x − 4)(x + 1)
y = (x − 2)(x − 4)(x + 1)
y = (x + 2)(x + 4)(x − 1)
y = (x − 2)(x + 4)(x − 1)

y = (x - 2)(x + 4)(x - 1)

Step-by-step explanation:

Given the zeros of a function say x = a and x = b, then

The factors are (x - a) and (x - b) and

y = (x - a)(x - b)

Given the zeros are x = 2, x = - 4, x = 1, then

the factors are (x - 2), (x - (- 4)) and (x - 1), that is

(x - 2), (x + 4), (x - 1) , thus

y = (x - 2)(x + 4)(x - 1)

13.33%

say 50 oranges, then 100 apples

80 are red, 20 are yellow

total fruit = 150

20chances out of 150 for yellow

20/150 = 13.33%
