What math the drawing a graph, for example: y = x^2, is taught? Is it algebra, calculus, or any other else? Thanks
Have you done any research on this? What have you found?askor said:What math the drawing a graph, for example: y = x^2, is taught? Is it algebra, calculus, or any other else? Thanks
Where are the turning points? What is the value of the function at those points? How does the function behave as ##x \to \pm \infty##?askor said:How do you draw the graph of ##y = 9x - \frac{x^3}{9}##?
I only know how to draw a graph of quadratic function. This function has a power of 3.

Then you should be able to do the steps that @fresh_42 put in the post above (possibly with some review). His list looks complete to me.askor said:Yes, I learned calculus of differentiation and integration.
THAT, or at least mostly.FactChecker said:It is taught in a class called algebra in high school (NOT abstract algebra), and often called pre-calculus in college.
If at least you have studied your Algebra 1, then you know to either (1) use a graphing tool, or (2) plug in values for x and evaluate corresponding y values; and then plot your points and draw your curve. Too simple? You learn more about such graphs in College Algebra.askor said:How do you draw the graph of ##y = 9x - \frac{x^3}{9}##?

One usually learns to graph polynomial functions, which your example here resembles, in College Algebra.askor said:How do you draw the graph of ##y = 9x - \frac{x^3}{9}##?

Polynomials can have coefficients from any ring or field.symbolipoint said:I said, "resembles" not "is". Some people will tell that a polynomial function has integer coefficients. I am not fully certain if this is or is not correct.
Only the exponents of the variables of a polynomial need to be positive integers (including 0).symbolipoint said:One usually learns to graph polynomial functions, which your example here resembles, in College Algebra.

I made a technical word choice mistake. The exponents in polynomials are the Whole numbers. "Integers" obviously the wrong word choice.MidgetDwarf said:Only the exponents of the variables of a polynomial need to be positive integers (including 0).
Drawing a graph in math class serves multiple purposes. It helps to visually represent data and relationships between variables, making it easier to understand and analyze. Graphs also allow for the identification of patterns and trends, which can aid in making predictions and solving problems.
The basic elements of a graph include the x and y-axis, which represent the independent and dependent variables respectively. The scale and units on each axis, the title, and labels for each axis are also important components. In addition, a graph may include a legend, gridlines, and data points or lines.
Graphs are used in various fields such as science, economics, and engineering to represent and analyze data. By learning how to draw a graph in math class, students develop skills that are essential for interpreting and communicating information in the real world. This includes identifying trends, making predictions, and understanding relationships between variables.
Some of the most commonly taught types of graphs in math class include line graphs, bar graphs, and pie charts. Line graphs are used to show trends over time, bar graphs are used to compare different categories, and pie charts are used to represent parts of a whole. Other types of graphs that may be taught include scatter plots, histograms, and box-and-whisker plots.
Drawing a graph requires students to analyze data, identify patterns, and make connections between variables. These skills are essential for problem-solving in math and other subjects. By understanding how to draw a graph, students can also use it as a tool to organize and interpret information, leading to more effective problem-solving strategies.
