In this video, the presenter explains how to use the quadratic formula to generate answers for X. They start by showing the formula and breaking it down into its components. Then, they demonstrate how to identify the values of A, B, and...

👉 Learn about the characteristics of a function. Given a function, we can determine the characteristics of the function's graph. We can determine the end behavior of the graph of the function (rises or falls left and rises or falls...

👉 Learn how to find the rate of change from graph. The rate of change is the rate at which y-values are changing with respect to the change in x-values. To determine the rate of change from a graph, a right triangle is drawn on the graph...

In this video, the teacher explains how context influences functions by examining a graph. They use the example of a volume function for a box to demonstrate how the x-intercepts represent the points where the volume is zero.

👉 Learn the basics to graphing sine and cosine functions. The sine graph is a sinusiodal graph with x-intercepts at x = 2n*pi, maximun value of 1 at x = pi/2 + 2n*pi and minimum value of -1 at x = -pi/2 + 2n*pi. The cosine graph is a...

This video explains the different parts of a linear model, including the coordinate plane, slope, y-intercept, and types of lines. It helps viewers understand how to identify and interpret these components in a linear equation, using...

👉 Learn how to graph linear equations written in standard form. When given a linear equation in standard form, to graph the equation, we first rewrite the linear equation in slope intercept form, (i.e. in the form y = mx + c, where m is...

Looking at conic sections.

👉 Learn how to find the x and y-intercepts of a rational function. The x-intercept(s) of a function occurs when y = 0 and the y-intercept(s) of a function occurs when x = 0. To find the y-intercept of a function, we plug in zero for x...

👉 Learn about graphing linear equations. A linear equation is an equation whose highest exponent on its variable(s) is 1. i.e. linear equations has no exponents on their variables. The graph of a linear equation is a straight line. To...

In this video lesson, mathematicians learn how to solve systems of two linear equations with no solution by graphing and finding the slope of the lines. The video explains that parallel lines, which have the same slope but different...

In this video, mathematicians learn how to identify and write equations of perpendicular lines by analyzing their slopes and y-intercepts. The video explains the concept using examples and demonstrates how to determine if two lines are...

In this video lesson, the teacher explains how to estimate solutions to systems of equations by graphing when both equations are in standard form. They demonstrate how to find the x and y-intercepts of each equation and graph them on a...

The "zeros" or "roots" of a quadratic function of a real variable x, correspond to the function's x-intercepts. It is not always easy to find the zeros of a quadratic function. However, quadratic functions can be factored into the...

The graph of a quadratic function in a single variable is a parabola. Setting that function equal to zero creates a quadratic equation, and the solutions to that equation are the "zeros" or "roots" of the function. In quadratic...
