A parabola is a curved graph produced by a quadratic function, one which contains a “squared” x-term.

How do you describe a curved graph?
A curve is common in rates of reaction graphs. A straight line would indicate a constant rate of reaction, while a curve indicates a change in the rate (or speed) of a reaction over time.Lines of best fit are also useful in identifying anomalous results and outliers which will not lie on the line of best fit.
What are the types of graph curves?
Types of Curves
- Simple Curve. A curve that changes its direction, but it does not intersect itself.
- Non-Simple Curve. The non-simple curve is a type of curve that crosses its path.
- Open Curve.
- Closed Curve.
- Upward Curve.
- Downward Curve.
- Area Between the curves.
What is it called when a graph flattens out?
You can see the difference in how the graph crosses the x-axis.If, on the other hand, the graph “flexes” or “flattens out” to some degree when it goes to cross the axis, then the zero is of a higher multiplicity; that is, it’ll be of multiplicity three, five, or higher.
What is it called when a graph goes down?
Decline/fall/drop are all synonyms, and they are all antonyms to rise/increase. All three can be used as a verb or noun, just like their antonyms. Go down is an antonym to go up. The parts of a graph: X-Axis: the horizontal portion of a graph.
What are the names of curves?
Rational curves
- Circle. Unit circle.
- Ellipse.
- Parabola.
- Hyperbola. Unit hyperbola.
What is the U shaped graph called?
parabola
The graph of the quadratic function is a U-shaped curve is called a parabola.
How do you describe the trend of a graph?
A trend is the general direction in which something is developing or changing over time. A projection is a prediction of future change. Trends and projections are usually illustrated using line graphs in which the horizontal axis represents time.
What is a turning point on a graph?
A turning point is a point of the graph where the graph changes from increasing to decreasing (rising to falling) or decreasing to increasing (falling to rising). A polynomial of degree n will have at most n – 1 turning points.
What is even multiplicity?
If the graph crosses the x-axis and appears almost linear at the intercept, it is a single zero. If the graph touches the x-axis and bounces off of the axis, it is a zero with even multiplicity. If the graph crosses the x-axis at a zero, it is a zero with odd multiplicity.
How do you describe the shape of a graph?
And, the shape describes the type of graph. The four ways to describe shape are whether it is symmetric, how many peaks it has, if it is skewed to the left or right, and whether it is uniform.A single peak over the center is called bell-shaped. And, a graph with two peaks is called bimodal.
What is it called when a line graph goes up and down?
So far, all of the graphs discussed have had a line that either always goes up or always goes down (the technical term for this is monotonic). Other relationships are more complex, with lines than can go up and down (called non-monotonic).
What is it called when a graph increases and decreases?
Strictly Increasing (and Strictly Decreasing) functions have a special property called “injective” or “one-to-one” which simply means we never get the same “y” value twice.Because Injective Functions can be reversed!
What is spiral curve?
The spiral is a curve of varying radius used to gradually increase the curvature of a road or railroad. Spiral curves are used primarily to reduce skidding and steering difficulties by gradual transition between straight-line and turning motion, and/or to provide a method for adequately superelevating curves.
What are simple curves?
A simple curve is a curve that does not cross itself.
What are special curves?
A plane curve is a curve that lies in a single plane. A plane curve may be closed or open. Curves which are interesting for some reason and whose properties have therefore been investigates are called “special” curves (Lawrence 1972).
What is an N shaped graph called?
Shape of the parabola
If a<0, then the parabola has a maximum point and it opens downwards (n-shaped) eg.
What is au shaped curve?
When a study reports a U-shaped curve it means that there is the lowest incidence of disease in the middle ranges, with peaks in both the lower and upper ranges. A graph of the outcomes would look something like the image on the right. A similar type of graph is sometimes reported as a “backwards-J” shaped curve.
What are V shaped graphs called?
The graph of the absolute value parent function is composed of two linear “pieces” joined together at a common vertex (the origin). The graph of such absolute value functions generally takes the shape of a V, or an up-side-down V. Notice that the graph is symmetric about the y-axis.
How do you describe a downward trend?
Verbs to describe a downward trend
Plunge and Plummet, when describing trends, have the same meaning.
Is there a downward trend?
If you refer to a downward trend, you mean that something is decreasing or that a situation is getting worse.
