if the value is negative, it opens downard
If the value of the variable is negative then the parabola opens downwards and when the value of variable is positive the parabola opens upward.
In a quadratic equation of the form (y = ax^2 + bx + c), the value of (a) determines the width of the parabola. If (|a|) is greater than 1, the parabola is narrower, indicating that it opens more steeply. Conversely, if (|a|) is less than 1, the parabola is wider, meaning it opens more gently. The sign of (a) also affects the direction of the opening: positive values open upwards, while negative values open downwards.
The coefficient of the squared term in a parabola's equation, typically expressed in the standard form (y = ax^2 + bx + c), is represented by the value (a). This coefficient determines the direction and the width of the parabola: if (a > 0), the parabola opens upwards, and if (a < 0), it opens downwards. The larger the absolute value of (a), the narrower the parabola.
When you look at the parabola if it opens downwards then the parabola has a maximum value (because it is the highest point on the graph) if it opens upward then the parabola has a minimum value (because it's the lowest possible point on the graph)
The value of ( b ) in a quadratic equation of the form ( y = ax^2 + bx + c ) affects the position and shape of the parabola. Specifically, it influences the location of the vertex along the x-axis and the direction in which the parabola opens. A larger absolute value of ( b ) can make the parabola wider or narrower depending on the value of ( a ), while the sign of ( b ) can shift the vertex left or right. Overall, these changes alter how the parabola intersects with the x-axis and its symmetry.
If the value of ( a ) in the equation ( y = ax^2 ) is positive, the parabola opens upwards. This means that the vertex of the parabola is the lowest point, and as you move away from the vertex in either direction along the x-axis, the value of ( y ) increases. Conversely, if ( a ) were negative, the parabola would open downwards.
In the standard form of a quadratic equation ( y = ax^2 + bx + c ), the value of ( a ) determines the direction and the shape of the graph. If ( a > 0 ), the parabola opens upwards, while if ( a < 0 ), it opens downwards. Additionally, the absolute value of ( a ) affects the width of the parabola: larger values of ( |a| ) result in a narrower graph, while smaller values lead to a wider graph.
Standard notation for a quadratic function: y= ax2 + bx + c which forms a parabola, a is positive , minimum value (parabola opens upwards on an x-y graph) a is negative, maximum value (parabola opens downward) See related link.
In a parabola defined by the equation ( y = ax^2 + q ), the parameter ( a ) determines the direction and width of the parabola, while ( q ) represents the vertical shift. To solve the effect of ( a ), consider its value: if ( a > 0 ), the parabola opens upward and is narrower as ( |a| ) increases; if ( a < 0 ), it opens downward and becomes wider as ( |a| ) decreases. The parameter ( q ) shifts the entire parabola up or down by ( q ) units without altering its shape. Adjusting these parameters allows for a comprehensive understanding of the parabola's position and orientation in the coordinate plane.
This is the coordinate of the vertex for a parabola that opens up, defined by a positive value of x^2.
If a parabola has no x-intercepts, it means that its graph does not intersect the x-axis. This occurs when the value of the quadratic's discriminant (b² - 4ac) is less than zero, indicating that the quadratic equation has no real solutions. Consequently, the parabola opens either entirely above or entirely below the x-axis, depending on the sign of the leading coefficient. If the leading coefficient is positive, the parabola opens upwards; if negative, it opens downwards.
The vertex is not affected by the direction that the parabola is facing. The vertex is the place where the two sides of the parabola meet. It is in the middle divides the shape in half. If you picture yourself looking at a bowl from the side and then imagining it as two dimensional, it would look like a parabola but for all of the filled in parts of the graph and the fact that the sides of the bowl don't continue on forever. The vertex is the bottom of the bowl, where the sides meet. You measure a vertex as you would a point; with a coordinate.
