Functions are relationships between quantities that change. Written and hosted by internationally acclaimed math educator Dr. Monica Neagoy, this video explores the definition of a function, its vocabulary and notations, and distinguishes the concept of function from a general relation. Multiple representations of functions are provided using the TI-Nspire, while dynamic visuals and scenarios put them into real-world contexts. Concepts explored: functions, relations, equations, quadratic functions, linear functions, multiple representations.

Topic

Functions and Relations

Definition

An absolute value function is a function that contains an algebraic expression within absolute value symbols. It is defined as 

$$ f(x) = |x| $$

where |x| denotes the absolute value ofx.

Description

The absolute value function is significant in mathematics because it measures the distance of a number from zero on the number line, regardless of direction. This function is linear in nature, as it can be broken into two linear pieces: one for 

$$ x \geq 0 $$

 and one for 

$$ x < 0 $$

Definition--Functions and Relations Concepts--Composite Function Definition--Functions and Relations Concepts--Composite Function Composite Function

Topic

Functions and Relations

Definition

A composite function is a function that is formed when one function is applied to the result of another function.

Description

Composite functions are significant in mathematics because they allow the combination of two functions to form a new function. This is denoted as (fāˆ˜g)(x) = f(g(x)). Composite functions are widely used in various fields, including computer science for function composition in programming and in calculus for chain rule applications. For example, if f(x) = 2x and g(x) = x + 3, then the composite function 

(fāˆ˜g)(x) = f(g(x)) = 2(x + 3) = 2x+6

Topic

Functions and Relations

Definition

Conic sections are the curves obtained by intersecting a plane with a double-napped cone.

Description

Conic sections include circles, ellipses, parabolas, and hyperbolas, which are fundamental in the study of geometry and algebra. These shapes are described by quadratic equations and have numerous applications in physics, engineering, and astronomy. For example, the orbits of planets are ellipses, and parabolic mirrors are used in telescopes and satellite dishes. The general quadratic equation for conic sections is 

Ax2 + Bxy + Cy2 + Dx + Ey + F = 0

A continuous function is a function that does not have any breaks, holes, or gaps in its domain.

Description

Continuous functions are fundamental in calculus and mathematical analysis because they allow for the application of limits, derivatives, and integrals. A function f(x) is continuous if, for every point š‘ c in its domain, 

lim xā†’c ā€‹ f(x) = f(c)

Topic

Functions and Relations

Definition

Distorting a function horizontally involves stretching or compressing the graph of the function along the x-axis.

Description

Horizontal distortions of functions are significant because they alter the input values while maintaining the overall shape of the graph. This is mathematically represented as 

f(kx)

where k is a constant. If k > 1, the function compresses horizontally, and if 0 < š‘˜ < 1, it stretches.
