For something to be a function, the input (x value) can ONLY HAVE ONE output (y value), so if x has multiple outputs, it is not a function

B is not a function because x = 2 and x = 9 has 2 outputs

Your answer is A

Answer:

Step-by-step explanation:

A represents a function.  Why?  Because all the x-values are unique (no duplications).

B does not represent a function.  Why?  Because the input 4 is repeated and has different y-values for this one input, and similarly the input 9 is repeated.

Hello there!

Answer:

4. dy/dx = -2

8. dy/dx = 1/2 x^(-3/2)

10/ dy/dr = 4 pi r^2

Step-by-step explanation:

4.  y = -2x+7

dy/dx = -2(1)

dy/dx = -2

8.  y = 4 - x^-1/2

 dy/dx =  - (-1/2x^ (-1/2-1)

 dy/dx = 1/2 x^(-3/2)

10.  y = 4/3 pi r^3

dy/dr = 4/3 pi  (3r^2)

dy/dr = 4 pi r^2
