Question

A. y = -6
B. 2 > y > -6
C. y ≤ -6
D. y ≥ -6

Answer 1

HI!!

Answer 2

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

Answer 3

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

Answer 4

\[y=\frac{1}{x2}x^2+2x-4\] 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

Answer 5

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

Answer 6

so D ?
