Polynomial function transformation help

In summary, the main differences between f(x) = x^3 and g(x) = x^3 - x are that f(x) is a perfect cube function while g(x) is a cubic function with a linear term. The -x term in g(x) shifts the graph downwards by one unit and affects the shape of the curve. Graphically, f(x) = 3x^3 + x is a cubic function with a steeper slope compared to g(x) and passes through the vertex at (0,0).

What is the difference between f(x)= x^3 , and g(x) = x^3 - x

What does that -x do to the function and how do you represent it graphically?

What about f(x) = 3x^3 +x


Homework Equations





The Attempt at a Solution



No idea, wolframalphad the graph but i don't get how to represent it or what it does to the graph.

Anyone help please??

There's a lot of differences. Are you just supposed to list all of the differences that you can find?

This is also not worded very well. What does it do to f(x) how? As far as graphing it goes, just pick a few points and plug them in.

Yes.. list the differences, I don't get it.

So...

x^3 has points

-2 -8
-1 -1
0 0
1 1
2 8


So doing x^3 + x would be

-2 (-2)^3 + -2 = -10
-1 -2
0 0
1 2
2 10

I graphed it... looks almost exactly like a linear function, passes thru vertex to.. is taht right then?

What is a polynomial function transformation?

A polynomial function transformation is the process of changing or manipulating the variables, coefficients, and exponents in a polynomial function to create a new function with different properties.

What are the common types of polynomial function transformations?

The most common types of polynomial function transformations include vertical and horizontal translations, horizontal and vertical stretches and compressions, and reflections over the x-axis or y-axis.

How do you graph a polynomial function transformation?

To graph a polynomial function transformation, you first need to identify the parent function and the type of transformation being applied. Then, you can use the properties of the transformation to plot points and create a new graph of the transformed function.

What is the purpose of polynomial function transformations?

The purpose of polynomial function transformations is to manipulate the shape, position, and properties of a polynomial function to better understand its behavior, make predictions, and solve problems.

What are some real-life applications of polynomial function transformations?

Polynomial function transformations have many real-life applications, such as in physics, engineering, and economics. For example, they can be used to model and predict the motion of objects, analyze growth patterns, and optimize production processes.
