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

The formula for the volume of pyramid is,

Here, B is base area and height of pyramid.
The volume expression for group 4 is,

Here, expression,

represents the base area and 9 represent the height of pyramid.
So height of the pyramid created by group 4 is 9.
Answer: 9
 
        
             
        
        
        
The length of the other leg is 12 cm
        
             
        
        
        
Applying BODMAS (Order of operations rule)
Where: B is for brackets
O is for 'of' which means multiplication
D is for division
M is for multiplication
A is for addition
S is for subtraction
<u>In this case:</u>
We start with addition then we go to addition and finally we subtract.
(78 × 13) - (8 × 78) + (26 × 78) - 78
= 1014 - 624 + 2028 - 78
= 1014 + 2028 - 624 - 78
= 3042 - 624 - 78
=2340
 
        
                    
             
        
        
        
$417.50 should be the correct answer you just multiply  the $7.25 to 30 and then add the $200.
