HI!!

2. misty1212

you do not have to do any work at all to solve this one!

3. misty1212

A $$y=-6$$ is not a range, it is just a number, so that is out

4. misty1212

$y=\frac{1}{x2}x^2+2x-4$ is a parabola that opens up so the range is $$y\geq \text{some number}$$ and you only have one choice that looks like that

5. misty1212

oops i meant $y=\frac{1}{2}x^2+2x-4$
