The graph of the function f(x) = (x +2)(x + 6) is shown below. What is true about the domain and range of the function? The doma
2 answers:
Answer: The domain is all real numbers, and the range is all real numbers greater than or equal to –4.
Step-by-step explanation:
Since, the given function is,
f(x) = (x+2)(x+6)
⇒
Which is the equation of parabola, ( that opened up)
Since, the vertex of the parabola is (-4,-4)
Therefore, the value of y will be not less than -4 ( because it is an upward parabola)
Thus, the range of the given function is all real number greater than or equal to –4.
Also, we know that the domain of all parabola is always the set of real numbers.
Thus, the domain of the given function is the set of all real numbers.
Therefore, first option is correct.

Answer:
the answer is c) 182.25
Step-by-step explanation:
The information provided gives you a scale that will ultimately allow you to determine the height of the larger cylinder.
Since it tells us the two are similar, we can use the scale to solve for the second height.
Set up your math like this:
h represents the height you are trying to find.
using a common multiple, you can solve for h.
16 times 4 is 64. so 729 divided by 4 is 182.25

Cal's go cart has a gas tank with the dimensions shown below. He uses a gas can that holds 1 gallon of gas, to fill the go cart tank. 1 gallon = 231 inches^3. How many full gas cans will it take to fill the go cart's gas tank?
Answer: 2 full gas cans
Step-by-step explanation:
From the image, we have the following dimensions:
length, l = 15.4 inches (in)
width, w = 10 in
height, h = 3 in.
The volume of the gas tank (which is rectangular) is given as:
NB: The unit of volume is cubic units. In this example, it is cubic inches.
The gas can being used to fill the tank holds 1 gallon of gas =
The total volume to be filled is of gas.
So, it will take full gas cans to fill the go cart's gas tank.
Therefore, the answer is 2.
