3 math questions , 10 POINTS♥

1. y=5/x
a) x = 0, y = 0;
b)x = 4, y = 1;
c)x = 0, y = 4;
d)x = 0, y = 0;

2. f(x)=8/x-4
a)x = 4, y = 0;
b)x = 0, y = 4;
c)x = 4, y = 0;
d)x = 0, y = –4;

3. y=1/x+4
a)x = 0, y = 0;
b)x = 0, y = 0;
c)x = 4, y = 0;
d)x = 0, y = 4;


thankss <3

1. y=5/x
a) x = 0, y = 0;
b)x = 4, y = 1;
c)x = 0, y = 4;
d)x = 0, y = 0;
None of them, cuz x isn't allowed to be 0, and b is just wrong.


2. f(x)=8/x-4
a)x = 4, y = 0;
b)x = 0, y = 4;
c)x = 4, y = 0;
d)x = 0, y = –4;
Again none of them, x can't be 0, and if x is 4, y would be -2.

3. y=1/x+4
a)x = 0, y = 0;
b)x = 0, y = 0;
c)x = 4, y = 0;
d)x = 0, y = 4;
None of them, x can't be 0, and if x is 4, y would be 5/4.

Concur -- as they are written, none of the given answers are right.

And even if, in #s 2 & 3, the denominators are supposed to be in (), like so ...

2. 8/(x-4)
3. 1/(x+4)

... all the answers are STILL wrong!

1-none of these are right. x is in the denominator and at 0 y would be infinity and at 4 y would be 1.2
Honestly none of these make any sense... sorry but these questions are wrong

None of those answers are correct
