What else can I help you with?
Is it true graph is reflected about the x-axis and the parabola opens down?
No. A parabola can open up or down.
What is a parabola graph?
A parabola is the result of an equation such as y=x2, or another variation of it such as y=2x2+1. This graph is shaped like a U or an upside down U, and this is shown by making a table. For every x value, the y value is squared. For example, if x=1, y will also equal 1; if x=2, y=4; if x=3, y=9; etc. These give you the coordinates (1,1), (2,4), and (3,9). When the coordinates are graphed the U-shaped graph (parabola) is formed.
When you graph a quadratic function what will the shape of the graph be?
A parabola. An arch opening either north or south of the x-axis depending on the sign of the coefficient (negative opens down, positive opens up).
What is the geometric significant of k in equation yx3 k?
This equation yx3 k is that of a parabola. The variable h and k represent the coordinents of the vertex. The geometrical value k serves to move the graph of the parabola up or down along the line.
How do you find a parabola opening up or down?
If you can mash the equation for the parabola into the form Y = Ax2 + Bx + C, then the parabola opens up if 'A' is positive, and down if 'A' is negative.
Is it true graph is reflected about the x-axis and the parabola opens down?
No. A parabola can open up or 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:\

What is the parabola?
A parabola is a type of graph that is not linear, and mostly curved. A parabola has the "x squared" sign in it's equation. A parabola is not only curved, but all the symmetrical. The symmetrical point, the middle of the parabola is called the vertex. You can graph this graph with the vertex, x-intercepts and a y-intercept. A parabola that has a positive x squared would be a smile parabola, and the one with the negative x squared would be a frown parabola. Also, there are the parabolas that are not up or down, but sideways Those parabolas have x=y squared, instead of y = x squared.
What would the graph of y equals -3x2-12x-13 look like?
an upside down parabola
What number if used as a slope would produce a graph steeper than the function y -5x?
-- Any number less than -5 is a steeper line sloping down. -- Any number greater than +5 is a steeper line sloping up.
When you graph a quadratic function what will the shape of the graph be?
A parabola. An arch opening either north or south of the x-axis depending on the sign of the coefficient (negative opens down, positive opens up).
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.
How does changing the constant affect a graph?
Changing the constant in a function will shift the graph vertically but will not change the shape of the graph. For example, in a linear function, changing the constant term will only move the line up or down. In a quadratic function, changing the constant term will shift the parabola up or down.
What is the geometric significant of k in equation yx3 k?
This equation yx3 k is that of a parabola. The variable h and k represent the coordinents of the vertex. The geometrical value k serves to move the graph of the parabola up or down along the line.
Considering the graph of a line with a negative slope what is true?
the line goes down from left to right as the absolute value of the negative slope get bigger, the graph of the line gets steeper as the absolute value of the negative slope gets smaller, the graph of the line gets less steep ( apex )
What different information do you get from vertex form and quadratic equation in standard form?
The graph of a quadratic function is always a parabola. If you put the equation (or function) into vertex form, you can read off the coordinates of the vertex, and you know the shape and orientation (up/down) of the parabola.
