B, because only the x values become negative
Answer:
D- (0.4) (1,6) (2,8)
Step-by-step explanation:
The first thing we want to do is to make the equation a function, so we put y by itself on one side,
Add 4 to both sides
y = 2x + 4 <<< This is the equation that we will use
So if we input these numbers in,
The answer seems to be D. Where if x = 0 then y = 4 and so on

Answer:
First get a common denominator then you divide the numerator then you get your answer
Step-by-step explanation:
Answer:C
Step-by-step explanation:
For every function; f(x) = y
Each value of 'x' produces only one output 'y'
A,B and D are not functions because this rule is violated. It is observed that on the graphs of A,B and D, there exists a value of x that produces two outputs(y).
Hence, C is the correct option as it produces only one output 'y' for each value of x.
