What are the restrictions for y <br> X=10/5+y
Naya [18.7K]

Answer:

y\ne-5

Step-by-step explanation:

So you have the equation:

  x=\frac{10}{5+y}. As you may know, you cannot divide by 0, so y has to be restricted in a way that the denominator is never equal to 0. So to find when y makes the denominator 0, simply set the denominator equal to 0, and solve for y. This gives you the equation: 5+y = 0, y=-5. So the y value CANNOT be equal to -5. Because it makes the denominator 0. so y\ne-5 would be the restriction.

Answer: The Answer is D.

Step-by-step explanation: IT is D because a FUNCTION DOES NOT suppose to hit more than 1 point. You can also use the vertical line test meaning take a pencil or pen hold it up and down and drag it across you screen or paper, and if it hits more than 1 point it is NOT a FUNCTION.
