Best ResponseYou've already chosen the best response.01. Graph y = –2x2 + 6. Describe what you see. The graph looks like a parabola that is shifted up by around 6 units, and is stretched by a factor of 1/2. It is also pointing down, since the coefficient of 2x^2 is a negative. This question is complete, the next question is what I need help with graph y = (1/10)x2 + 6. Describe what you see. How is what you observe here different from what you observed in part A?

Best ResponseYou've already chosen the best response.0So is this graphed shifted by 5 instead of 6? Or is it also 6?

Best ResponseYou've already chosen the best response.1Well, whenever you graph a second degree function, and it represents a parabola, it'll look like this: \[y=Ax^2 + Bx + C\] This is pretty much the equation of the parabola and we can find the orientation, or the cancavity if you like, by looking at the sign that "A" has, if it is negative, the parabola opens downwards, if "A" is positive, it opens upwards. So, in the function you were given: \[y=\frac{ 1 }{ 10 }x^2+6\] "A" which in this case is "1/10" is negative, so it opens downwards as well.

Best ResponseYou've already chosen the best response.0So when you say it opens downwards, you mean that it would look like a hill then?

Best ResponseYou've already chosen the best response.1yes, but there are more things you have to determine, like where it cuts the xaxis and where it cuts the yaxis.
