Is it true graph is reflected about the x-axis and the parabola opens down?
No. A parabola can open up or down.
The equation below describes a parabola. If a is negative which way does the parabola open y ax2?
Down
Given the standard equation for a parabola opening up or down which way does a parabola open when the coefficient of the x2term a is negative Up or down?
down
In which direction does the parabola?
A parabola can open left, down, right, or left on a graph, if that's what you mean:\
Which way does a parabola open when the coefficient of its x2term a is negative?
DOWN!
Does the parabola open up or down?
It does both depending if it is positive or negative
Given the standard equation for a parabola opening up or down which way does a parabola open when the coefficient of the x2 term a is positiveUp or down?
In that case it opens upwards.
When will parabola open down?
In classic geometry, it opens down when the directrix is above the focus.In analytical (coordinate) geometry, if the equation of the parabola isy = ax^2 + bx + c, it opens down if a < 0.
The equation y -3x2 describes a parabola. Which way does the parabola open?
The given terms can't be an equation without an equality sign but a negative parabola opens down wards whereas a positive parabola opens up wards.
What makes a parabola a parabola?
A parabola is a quadratic figure. It is an intersection of a right conical surface, a plane parallel to a generating straight line of the surface. Basically, it's an arc shape. It can open up, down, left, or right.
The maximum or minimum of a parabola depending on whether the parabola opens up or down?
A parabola opening up has a minimum, while a parabola opening down has a maximum.
What equation describes a parabola that opens up or down and whose vertex at the point (hv)?
This is called the 'standard form' for the equation of a parabola:y =a (x-h)2+vDepending on whether the constant a is positive or negative, the parabola will open up or down.
