## What is vertical line test for a function?

The vertical line test is used to determine if a graph of a relationship is a function or not.

if you can draw any vertical line that intersects more than one point on the relationship, then it is not a function..

## What is simple curve?

A simple curve is a curve that does not cross itself.

## What is a curved shape?

1. curved shape – the trace of a point whose direction of motion changes. curve. bell-shaped curve, Gaussian curve, Gaussian shape, normal curve – a symmetrical curve representing the normal distribution.

## What is the formula for a curved line?

Use the formula m = (y2 – y1) / (x2 – x1), in which “m” is the slope and (x1, y1) and (x2, y2) are points on the line. In the example, m = (1 – 0) / (2 – 0) = 1/2.

## Can straight lines curve?

What About Curves? A curve is not a straight line, just as a straight line is not a curve. A curved line contains points that are not linear to two given points. The curve moves in other directions from the straight line created by joining collinear points.

## What is a curved line distance?

Curved distance on a map can be measured by a strip of paper, a thread, a opisometer. Use a ruler to measure the distance between the two places. If the line is quite curved, use a string to determine the distance, and then measure the string. Find the scale for the map you’re going to use.

## How do you describe the results of a graph?

Describing language of a graphUP: increase / rise / grow / went up / soar / double / multiply / climb / exceed /DOWN: decrease / drop / fall / decline / plummet / halve / depreciate / plunge.UP & DOWN: fluctuate / undulated / dip /SAME: stable (stabilised) / levelled off / remained constant or steady / consistent.More items…

## How do you explain a graph and a chart?

Graphs and charts are visual representations of data in the form of points, lines, bars, and pie charts. Using graphs or charts, you can display values you measure in an experiment, sales data, or how your electrical use changes over time. Types of graphs and charts include line graphs, bar graphs, and circle charts.

## How do you describe a line on a graph?

The formal term to describe a straight line graph is linear, whether or not it goes through the origin, and the relationship between the two variables is called a linear relationship. Similarly, the relationship shown by a curved graph is called non-linear.

## Are lines straight?

A line can be straight or curved. The word line usually means a straight line. A straight line is the shortest distance between two points. … The edge of a circle is not straight and is an example of a curve.

## What does a curved line on a graph mean?

If the velocity is changing, then the slope is changing (i.e., a curved line). … If a position graph is curved, the slope will be changing, which also means the velocity is changing. Changing velocity implies acceleration. So, curvature in a graph means the object is accelerating, changing velocity/slope.

## Is a line of best fit curved or straight?

a line or curve of best fit on each graph. Lines of best fit can be straight or curved. Some will pass through all of the points, while others will have an even spread of points on either side. There is usually no right or wrong line, but the guidelines below will help you to draw the best one you can.

## How do you describe a curve on a 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 can also be extrapolated (extended).

## How do you find the slope of a curved line?

Finding slope. To find the slope m m m of a curve at a particular point, we differentiate the equation of the curve. If the given curve is y = f ( x ) , y=f(x), y=f(x), we evaluate d y d x \dfrac { dy }{ dx } dxdy or f ′ ( x ) f'(x) f′(x) and substitute the value of x x x to find the slope.

## What is a curved line called?

In mathematics, a curve (also called a curved line in older texts) is an object similar to a line, but that does not have to be straight. … Level curves and algebraic curves are sometimes called implicit curves, since they are generally defined by implicit equations.

## Is a curved line a function?

A function can only have one output, y, for each unique input, x. If a vertical line intersects a curve on an xy-plane more than once then for one value of x the curve has more than one value of y, and so, the curve does not represent a function.
