What is the equality of complex numbers
👉 Learn how to solve rational equations. A rational expression is an expression in the form of a fraction where the numerator and/or the denominator are/is an algebraic expression. There are many ways to solve rational expressions, one...

Learn How to Find the Domain of the Composition of Two Functions
Learn how to compose two functions where one or both of those functions is/are radical. To compose two functions means to express one of the functions as a function of the other function. This is done by replacing the input variable of...

Learn how to determine the asymptotes and intercepts
👉 Learn how to find the vertical/horizontal asymptotes of a function. An asymptote is a line that the graph of a function approaches but never touches. The vertical asymptote is a vertical line that the graph of a function approaches but...

Identify Special Solutions of Compound Inequalities
In this video lesson we will learn how to identify Special Solutions of Compound Inequalities. We will learn that some compound inequalities have no solution, a solution of all real numbers, one solution or a one inequality solution. We...

How to Solve Absolute Value Inequalities
In this video lesson we will learn about absolute value inequalities. We will discover that a less than or less than or equal to absolute value inequality will have an AND solution set. We will learn that a greater than or greater than...

How to graph secant and label the parts
👉 Learn how to graph a secant function. To graph a secant function, we start with the cosine graph by first determining the amplitude (the maximum point on the graph), the period (the distance/time for a complete oscillation), the phase...

Find the domain range and period for cosecant and secant functions
👉 Learn the basics of graphing the secant and the cosecant graphs. Recall that the secant is the reciprocal of the cosine while the cosecant is the reciprocal of the sine. Also recall that the cosine graph is a sinusoidal graph with...

How to graph the reciprocal function and identify the characteristics
👉 Learn how to graph the reciprocal function. A reciprocal function is a rational function whose expression of the variable is in the denominator. A reciprocal function is of the form f(x) = a / (x + h) + k, where h is the vertical...

How to graph a rational function with a hole
👉 Learn how to graph a rational function. To graph a rational function, we first find the vertical and horizontal or slant asymptotes and the x and y-intercepts. After finding the asymptotes and the intercepts, we graph the values and...

Find inverse of a rational equation with two variables in numerator and denominator
👉 Learn how to find the inverse of a rational function. A rational function is a function that has an expression in the numerator and the denominator of the function. The inverse of a function is a function that reverses the "effect" of...

Quotient of two linear functions to determine the domain
👉 Learn how to divide two functions. We will explore the division of linear, quadratic, rational, and radical functions. To divide two functions, we simply algebraically divide the rules (contents) of the two functions. We will then...

Use the inverse of a function to determine the domain and range
👉 Learn how to find the inverse of a linear function. A linear function is a function whose highest exponent in the variable(s) is 1. The inverse of a function is a function that reverses the "effect" of the original function. One...
