1. The change in water level of a lake is modeled by a polynomial function, W(x). Describe how to find the x-intercepts of W(x) and how to construct a rough graph of W(x) so that the Parks Department can predict when there will be no change in the water level. You may create a sample polynomial of degree 3 or higher to use in your […]

1. George tells you that when variables are in the denominator, the equation becomes unsolvable. George explains, “There is a value for x that makes the denominator zero, and you can’t divide by zero.” Demonstrate to George how the equation is still solvable and explain your reasoning. 2. When looking at the rational function , Bella and Edward have two different thoughts. Bella says that […]

Use an outside source to search for a quadratic equation that models something from your daily life. Solve the equation in two ways. Discuss which method you liked better and why. In your responses to peers, compare and contrast your preferences for how to solve quadratic equations. (attached are disscusions) Hello everyone, There is a luxury 5hr river tour in brazil that goes 25 km […]

Part of problem solving isn’t always about finding an answer, but understanding what you think might happen. How likely is it to rain during your commute? What are your chances of picking a winning lottery number or of getting a raise? When we talk about the likelihood of something happening or not, what we’re really referring to is probability. And understanding how to calculate probable […]
