The quadratic regression equation for this data set is 
.
<h3>
What is the general form of a quadratic equation?</h3>
The general form of the quadratic equation is given by;
Where; a, b, and c are the constants.
x; 0 1 2 3 4 5
y; 2.82 3. 29 3. 46 3. 33 2. 88 2. 24
From the table when the value of x = 0 the value of y is 2.82.
Then,
From the table when the value of x = 3 the value of y is 3.33.
From the table when the value of x = 5 the value of y is 2.24.
And the value of b is;
Therefore,
The quadratic regression equation for this data set is;
Hence, the quadratic regression equation for this data set is .

Answer:
(-∞, -4] U [-1, ∞)
Step-by-step explanation:
The quadratic expression factors as ...
x^2 +5x +4 = (x +4)(x +1)
The zeros of this expression are where these factors are zero, at x=-4 and x=-1. The product is negative when one factor is negative and the other is positive, in the region -4 < x < -1. It is non-negative elsewhere. f(x) is defined where the quadratic is not negative, on the union of intervals ...
(-∞, -4] U [-1, ∞)
