# Write an expression to show the sum of x and y graphs

Search form Search Problem: Jensen likes to divide her class into groups of 2. Use mathematical symbols to represent all the students in her class. Using interval notation, we say that the function is decreasing on the interval -3, 2 increasing on -infinity, -3 and 2, infinity Exercise 3: Answer Some of the most characteristics of a function are its Relative Extreme Values.

Points on the functions graph corresponding to relative extreme values are turning points, or points where the function changes from decreasing to increasing or vice versa. Let f be the function whose graph is drawn below.

Note that f a is not the smallest function value, f c is. However, if we consider only the portion of the graph in the circle above a, then f a is the smallest second coordinate. Look at the circle on the graph above b. While f b is not the largest function value this function does not have a largest valueif we look only at the portion of the graph in the circle, then the point b, f b is above all the other points.

So, f b is a relative maximum of f. Indeed, f c is the absolute minimum of f, but it is also one of the relative minima. Here again we are giving definitions that appeal to your geometric intuition. The precise definitions are given in your text.

Return to Contents Approximating Relative Extrema Finding the exact location of a function's relative extrema generally requires calculus. However, graphing utilities such as the Java Grapher may be used to approximate these numbers. Suppose a is a number such that f a is a relative minimum. In applications, it is often more important to know where the function attains its relative minimum than it is to know what the relative minimum is.

We will call the point 2,0 a relative minimum point. In general, a relative extreme point is a point on the graph of f whose second coordinate is a relative extreme value of f. When you display the graph of f in the default viewing rectangle you see that f has one relative maximum point near -1,4 and one relative minimum point near 2, The approximations -1,4 and 2,-8 are not very close to the real relative extreme points, so we will use the zoom and trace features to improve the approximations.

When you click the Trace button, a point on the graph of f is indicated with a small circle. The coordinates of that point are reported in the two text boxes near the Trace button. If you select a larger Step Size from the pull down menu, then the trace point moves farther with each click.

It is possible to move faster with the enter key than with the mouse.

Using the default view, the lowest point found while tracing near the minimum point is 1.There are three output files specified, and for the first two, no -map options are set, so ffmpeg will select streams for these two files automatically.. timberdesignmag.com is a Matroska container file and accepts video, audio and subtitle streams, so ffmpeg will try to select one of each type.

For video, it will select stream 0 from timberdesignmag.com4, which has the highest resolution among all the input video streams. Examples: x, y, a, h, p, etc. It is critical that you know these words or phrases to be successful in writing or interpreting any given algebraic expression.
