Answer:

f(x) = -(x+2)(x-1)

Step-by-step explanation:

We know the zeros are at 1 and -2

f(x) = a *(x-b1)(x-b2) where b1 and b2 are the zeros and a is a constant

f(x) =a(x-1)(x- -2)

f(x) =a(x-1)(x+2)

We know that a must be negative since the parabola opens down so

The only choice is choice D where a = -1

f(x) = -(x+2)(x-1)

The difference between two integers is 2. The larger integer is 11 less than twice the smaller. Find the smaller integer.

mr_godi [17]

Answer:

The smaller integer (y) is 3.

Step-by-step explanation:

$x - y = 2 = > y = x - 2\\ x = 2y - 11 \\ x = 2(x - 2) - 11 \\ x = 2x - 4 - 11 \\ x = 2x - 15 \\ 3x = 15 \\ x = 5 \\ \\ x - y = 2 \\ (5) - y = 2 \\ - y = - 3 \\ y = 3$

Therefore, the smaller integer, represented by y, is equal to 3.
