Answer:
Step-by-step explanation:
But the formula for the volume of a sphere is volume is equal to 4/3 pi r cubed, where r is the radius of the sphere. So they've given us the diameter. And just like for circles, the radius of the sphere is half of the diameter.
Given:
The function is

To find:
The inverse of the given function.
Solution:
We have,

Put f(x)=y.

Interchange x and y.

Isolate the variable y.




Putting
, we get

For
,




It means for function
and for inverse function
because the range of the function is the domain of inverse function.
Therefore,
for
.
Answer:
and yea
Step-by-step explanation:
Answer:
(1, 4) and (1,3), because they have the same x-value
Step-by-step explanation:
For a relation to be regarded as a function, there should be no two y-values assigned to an x-value. However, two different x-values can have the same y-values.
In the relation given in the equation, the ordered pairs (1,4) and (1,3), prevent the relation from being a function because, two y-values were assigned to the same x-value. x = 1, is having y = 4, and 3 respectively.
Therefore, the relation is not a function anymore if both ordered pairs are included.
<em>The ordered pairs which make the relation not to be a function are: "(1, 4) and (1,3), because they have the same x-value".</em>
