its a concave up parabola, symmetric about the y axis, cuts the y axis at - 4 and cuts the x axis at \[x = \pm \frac{2}{\sqrt{3}}\]
yes i understand that but does the line point up or down I graphed it on my paper as being up but im not 100 % sure if that's correct
concave up... means |dw:1364412258382:dw|
ohhh its up are you sure
|dw:1364412296139:dw|
The general from of a parabola is \[y = ax^2 + bx + c\] the value of a determines the concavity if a is negative the parabola is concave down is a is positive its concave up. in your question a = 3 which is positive, so concave up.
thans so much :)
