When graphing why should you draw a smooth line that reflects the general pattern rather than automatically connect the data points?

If you want to draw a good graph, draw a smooth curve. If you just draw straight lines connecting the points, depending on which points you pick, you could get a really inaccurate graph.
So, always plot a lot of points before drawing a line, and draw a smooth line!

The equation AX plus BY is the general equation for a?
AX + BY is not an equation .AX + BY + C = 0is the general equation for a straight line.
Why quadratic equation is called quadratic?
In mathematics, a quadratic equation is a polynomial equation of the second degree. The general form is Where x represents a variable, and a, b, and c, constants, with a ≠ 0. (If a = 0, the equation becomes a linear equation.) The constants a, b, and c, are called respectively, the quadratic coefficient, the linear coefficient and the constant term or free term. The term "quadratic" comes from quadratus, which is the Latin word for "square." Quadratic equations can be solved by factoring, completing the square, graphing, Newton's method, and using the quadratic formula (given below). One common use of quadratic equations is computing trajectories in projectile motion. Because it is in the form of ax^2+bx+c=0
What does non linear graph mean?
a non linear graph pretty much means the points on the graph do not create a straight line. in order for a graph to be linear both the x axis and y axis have to increase/decrease at a constant rate, while in a non-linear graph when you connect the point it creates a line that isn't straight. however, in experimental data if the points are a bit off, but still in one general area, it can be considered linear.
In general the y intercept of the function Fx equals a bx is the point?
in general, the y-intercept of the function f(X)= axb^x is the point__.
When graphing why should you draw a smooth line that reflects the general patter rather that automatically connect the data points?
It is not true to say that you should automatically draw a smooth line. It depends on what you are attempting to do. A smooth line may be a good indicator of a trend but such a line is useless if you want to find out whether or not there is any periodicity in the data. For the latter you must join the data points and look for periodic patterns.
Why should you draw a smooth line that reflects the general pattern rather than automatically connect the data points?
A line of best fit emphasizes the overall trend shown by all the data taken as a whole whereas if you just "connect the dots", the lines could be all over the place.
A smooth line that reflects the general pattern in a graph?
The line that reflects the general pattern of a graph is called a trend line.

How do you connect to the internet in Fedora?
Assuming you are using the default gnome 3 desktop, go to settings and select network settings. There should be a tab called as 'general'. In that check 'automatically connect to this network'.. Then go to the 'Ipv4 settings' and 'Ipv6 settings' tab and set : Method - automatic. Do this in both the tabs and click on save . This should work..

Why should you draw a smooth line that reflects the general pattern rather than simply connect the data points?
If the question is about a scatter plot, the the data points will be not be located on a straight line but will be displaced by a random element. Connecting the points will give a zigzag line which will fit all the data point exactly but will be of little use in terms of explanatory or predictive value. A smooth line will.
What types of calculators have a graph maker included?
Graphing Calculators such as those created by Texas Instruments have graph maker features as a core function of the device. Children in High Schools across North America have used graphing calculators in their course work.

There are some things that your body does automatically. Breathing, blood flow, nerves transmitting pain and feelings to the brain, and general internal and external movement of joints are things the body does automatically when there is no medical issues present.
What reflects across the x-axis?
If a function reflects along the x-axis, that indicates that it has both negative and positive solutions. For example, y = x2 reflects along the x-axis because x2 = -x2. In general, a function will reflect along the x-axis if f(x) = f(-x).
