Answer:
Domain & Range are both all real numbers.
Step-by-step explanation:
i
If this was a traditional parabola, the range would be y<=4. However, the arrow on the left going back up means eventually y will go to both positive & negative infinity.
Answer:
the second one, but I'm not sure if I'm right
I believe the answer is d, because i cant find a pattern where x and y are directly connected.
The least common denominator would be 2x^2
that is because you would have to multiply the first fraction by 2x
but you can't just somehow simplify 2x^2, it wouldn't be right
4/x * -4/2x^2
2x*4/(2x*x) * -4/2x^2
8x /2x^2 * -4/2x^2
Then you would complete it
Hope this helps :)
