Answer:
D,
Step-by-step explanation:
D would be the only one that doesn't represent a function because the y-value never changes while the x-value does.
The answer for x=-1
The answer for y=-5/2
I believe these are correct
Answer:

Step-by-step explanation:
<em>The correct question is</em>
If f(x)=3x-1 and g(x)=x+2, find (f-g)(x)
we know that
(f-g)(x) is equal to subtract the function g(x) from the function f(x)
so

substitute the given functions

Remove the parenthesis

Answer:
The new point is at (5, -5)
Step-by-step explanation:
When a point is being translated down, they are being subtracted on the y-value. So all you have to do is subtract 9 from 4 and we end up with -5, our new y-value.
(5, -5)
M = 9
o = 7
m + 0 = 9 + 7 = 16
Hence, the answer is 16.
