Answer:
4: No
5: A
Step-by-step explanation:
4: The mapping does now represent a function. In a function each x value can only have 1 corresponding y value ( meaning that the x values can not repeat.) In the mapping the x value 3 corresponds with 2 y values therefore the mapping is not a function.

Formula for volume of a cylinder =
Where r = radius and h = height
The cylinder shown has a given diameter of 22ft and a given height of 10ft
In order to use the formula we must convert the diameter to radius.
To do this we divide the diameter by 2 ( this is because the radius is equal to half the diameter )
so radius = 22/2 = 11
Now we plug in the dimensions into the formula
Remember, it says " Leave your answer in terms of pi," therefore we do not apply pi and leave it as 1210π
We can conclude that the answer is A
We cannot agree with Danika. Why? Well, The reasoning is given as follows:
Two functions are inverses of each other if and only if it is true that the composition function is given by:
Everything is ok up to this point, right?. But let's prove that this is not fulfilled for these functions, then:
<span>
As you can see we did not obtain the function that matches the definition of </span>inverse functions. For that reason <em>we can't agree with Danika</em>.
