Two terms: y = –2x^2 + 6 y = -0.1x^2 + 6
You are basically making a coaster Create an equation that will be steeper than both equations, and explain your reasoning.Is what I needed help with
I know they are both conics y = (-1/10) x2 + 6 has the lines of the conic touch -8 and 8 on the x-axis, with the conic from question A has it touching -2 and 2 on the x - axis

Thank you for coming
"steeper" means a small step in x causes a large step in y y = –2x^2 + 6 here, if we move from x=0 (y=6) to x=1 (y=4) y goes down by 2 if we put a bigger number in front of the x, it gets steeper y = -4x^2 + 6 at x=0 y = 6 at x=1 y = 2 we go down by 4, which is a steeper drop
This is the answer?
Create an equation that will be steeper than both equations, that means make the coefficient of the x^2 term bigger (in absolute terms)
Alright then So like you said y = -4x^2 + 6 for the first one y = -(1/20)x^2 + 6
I think they just want ONE equation that is steeper than BOTH.
So y = -4x^2 + 6
That will do. But you have to explain your reasoning. In y = ax^2 +b, increasing the magnitude of a, that is the absolute value of a, has the effect of stretching the graph vertically, making it steeper.
Thanks @aum
