Respuesta :
Answer: (8,3) and (8,-3)
Step-by-step explanation:
This is because there can not be 2 repeating x values (the line test)
Option C is correct - (8, 3) and (8,-3)
We have a linear equation in two variables as - [tex]x = y^{2} - 1[/tex]
We have to find out which ordered pairs of the mentioned are sufficient to prove that the equation is not a function.
In which condition an equation is not a function?
Plot the graph of the equation, if for one value of x more than one value of y exists then the equation is not a function.
The equation given to us - [tex]x = y^{2} - 1[/tex]
[tex]x +1 = y^{2}[/tex]
Now, we have to find out for what value of x and y, the equation is not a function -
For the coordinates (8, 3) and (8, -3) -
8 + 1 = 3 x 3 = 9
and
8 + 1 = -3 x -3 = 9
But, here for one value of x =8, we have two values of y = 3, -3, which is never possible in a function. Hence, Option C is correct.
