He graph of the function f(x) = –(x + 6)(x + 2) is shown below.
1 answer:
The domain of the function is all real numbers, the range of a function is y ≤ 4
<h3>What is a function?</h3>It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a function:
f(x) = –(x + 6)(x + 2)
If we plot this function on the coordinate plane, we will see it is a graph of a quadratic function.
Here the no other details are given.
But we can say:
- The domain of the function is all real numbers.
- The range of a function is y ≤ 4
- The x-axis intercept will be at (-6, 0) and (-2, 0).
Thus, the domain of the function is all real numbers, the range of a function is y ≤ 4

Solution:
As we can see according to the coordinate diagram, the length of the rectangle is 5 unit long in the negative x axis and negative 3 in the y axis, now with one vertex at origin.
Therefore there is 1 vertex that have their y coordinate as zero and other whose x coordinate is 0.
Hence, the value of two vertex that are on line with the axis are (-5, 0) and (0.-3).
To the value of x and y we use the coordinates (-5, 0) and (0, -3), as we can see the value of x axis is -5 and the value of y =3.
Hence, the value of (x, y) = (-5, 3).
And the other coordinates are (-5, 0) , (0,-3) and (0, 0)
