Question

What is the domain of the function y=^x=6-7?

Answer 1

(x ,y) =(-1,-1)

Explanation:

`\left \{ {{y=6-7} \atop {x=6-7}} \right.`

`\left \{ {{y=-1} \atop {x=-1}} \right.`

(x,y) =(-1,-1)

Answer 2

The domain would be -1

Explanation:

The given function is

`y=x=6-7`

This expression expresses that both expressions are equal, that is

`y=6-7=-1\\x=6-7=-1`

So, basically the function can be expressed as
`(-1,-1)`. In other words, the function is only a point.

Therefore, the domain would be -1 and the range -1. Because the only element for x is -1 and the only element for y is -1.
