Graph the family of polynomials in the same viewing...

Graph the family of polynomials in the same viewing rectangle, using the given values of $c .$ Explain how changing the value of $c$ affects the graph.
$$P(x)=c x^{3} ; \quad c=1,2,5, \frac{1}{2}$$

Key Concepts

Leading Coefficient

The leading coefficient, which is the coefficient of the term with the highest power in a polynomial, primarily affects the vertical stretch or compression of the graph. Changing the leading coefficient alters the steepness of the graph without affecting its overall shape, causing the graph to be stretched away from or compressed towards the x-axis.

Family of Functions

A family of functions is a group of functions that share a common form but differ by one or more parameters. By varying these parameters, one can analyze how slight modifications in the function’s definition influence its graphical behavior and properties, allowing for comparisons across different instances of the function.

Polynomial Functions

Polynomial functions are algebraic expressions consisting of variables raised to non-negative integer powers and multiplied by coefficients. They can be represented in the form P(x) = ax^n + bx^(n-1) + ... + k, and their graphs exhibit smooth and continuous behaviors with various end behaviors depending on the highest power term.

Graph Transformations

Graph transformations include operations such as translations, reflections, stretches, and compressions that modify the graph of a function. In particular, vertical scaling (stretching or compressing) is achieved by multiplying the function by a constant, which changes the rate at which the function values increase or decrease without changing the location of the x-intercepts or the overall shape of the graph.
