A function is a process or a relation that associates each element x of a set X to a single element y of another set Y.
A. The equation 
represents vertical line. This is not a function, because one element x=5 is associated to all (not one) elements of 
B. The equation 
represents parabola that goes in positive x-direction. This is not a function, because each 
is associated to two different y. For examlpe, when x=10, then 
C. The equation 
represents parabola that goes in positive y-direction. This is the function, because for each x is associated only one y.
D. The equation 
represents hyperbola. This is not a function, because for one x there are two different possible y.
Answer: correct choice is C
Answer: 
Step-by-step explanation:
Given
Box A has a volume of 
Box B is similar to box A such that box A dimension is multiplied by 4 to get the box B
So, each length is 4 times the box A and volume is the cube of the side.
Thus, the volume of box B is 
the volume of box A
The volume of box B is
Answer:
-5/3
Step-by-step explanation:
To solve this just plug in 7 wherever you see an x
we have
3/(7+2)-sqrt(7-3)
3/9-sqrt(4)
.3333-2= -5/3
Answer:
This is how you find the comosite figure
Separate the figure in simpler forms, which can be discovered in a composite figure field. Then merge the fields. Keep in mind that none of the simple figures have overlaps. Example 1: Find the area shown below for the composite form
