If a is positive which way does the parabola open?
Upwards like a letter U
The equation below describes a parabola. If a is positive which way does the parabola open y ax2?
right apex. hope that helps
What way does the parabola open if a is greater than 0?
If a is greater than zero then the parabola opens upward.
How do you figure out if a parabola is stretched or shrunk?
Assuming the parabola is of the form y = ax^2 + bx + c or y= a(x-h)^2 - k, you look to the 'a' coefficient to determine whether the parabola has undergone a vertical "stretch" or "shrink." If a>1, then it's a stretch. If 0<a<1, then it's a shrink. If, by the way, the a is negative, this test still works... just ignore the negative sign. So if for example a = -2/3, it's a shrink, but if a = -3 it's a stretch. (Incidentally, the negative sign makes the parabola "reflect" over the x-axis.)
A graph made up of connected lines or curves is called?
it depends which way it curls. if it goes to the right its a hyperbola line grpah and if it goes to the left its a parabola line graph.
