Nsccalp: Math: Finding the Equation Given Three Points (Quadratic Functions)

How many points are needed to define a unique parabola? Individuals work with data to answer this question. Ultimately, they determine the quadratic model when given three points. The concept is applied to data from a dropped...

Put all that algebra learning to use! Using algebraic strategies, learners solve three-variable systems. They then use the three-variable systems to write a quadratic equation given three points on the parabola.

Linear, exponential, now it's time for quadratic patterns! Learners build on their skills of modeling patterns by analyzing situations with quadratic functions. The sixth module in the Algebra I series has pupils analyze multiple...

Sal uses the elimination method to simplify a system of three variables. Next, he employs the substitution method to check his solution. This resource would nicely complement any lesson on this topic.

Linear functions just never go away! Given two points on the inverse of a function, mathematicians find the equation of the original function using a linear model. The lesson captures the importance of understanding the properties...

Reinforce your young mathematicians' linear equation-writing skills. A video lesson does a nice job explaining the steps of writing the equation of a line when given two points. It begins by giving scholars a problem to try on their own...

How many different ways can three planes intersect? The interactive provides three movable planes. Pupils manipulate the planes to determine the number of solutions possible based upon their intersections.

Short and simple. X equals negative b divided by two(a) is the formula used to find the axis of symmetry. If the quadratic equation is in standard form, identify the values for a, b, and c and plug the values into the formula. Do the...

Given two points on a line, write an equation in point-slope form. But what's the slope? Oh, you have to figure out the slope first. That can be done given two points. Just use the rise over run slope formula. This isn't so hard after...

This is an introductory video on how to identify a quadratic function. This video explains what a quadratic function is and what the graph of a quadratic function looks like. The instructor goes through 4 examples of quadratic functions...
