Question #e44d3

Answer 1

No, the graph would be modelled by
`y=-1/4(x+1)^2 + 2`

Explanation:

Whenever you multiply a number by `-1`, the numbers stay the same, but the symbol in front changes. For instance,
`-1*color(green)(+)4=color(green)(-)4`, or
`-1*color(red)(-)79.5=color(red)(+)79.5`

You made a mistake in your calculations, in that you supposed that
`-1*0.25=-1/16`, when in fact
`-1*0.25=-0.25`, which makes the graph of `x` be
`y=-1/4(x+1)^2 + 2`

graph{y=-1/4(x+1)^2 + 2 [-20, 20, -10, 10]}

I hope I helped!
