First, every time when you ask question like this about function you must give elements of the initial set.

Definition of the function is - Every element of the starting set (domain- x)

must be related to only one element of the second set ( codomain-range-y).

In your case you have element (coordinate) x=3 which is in the relation with two elements (coordinates) y=2 and y=5 and that is relation but not function.

Good luck!!!

The answer to your question is,

No. It is not a function. Reasoning behind this is because there are repeating numerators. You can NOT have two of the same numerator as that will not form correctly if graphed. Two threes.

How many solutions does the system have? y=−2x−4 y=3x+3

Answer:

One Solution

Step-by-step explanation:

First substitute the y in the first equation with the second equation to get

-2x-4=3x+3

since theres a variable of both sides, you subtract the variable with the least coefficient, in this case, you add 2x to both sides to get

-4=5x+3

subtract the constant on both sides to get
