==== **__ 5.1: __ ** **List the following words and give a mathematical definition in your own words on your wikispace. Remember, you may edit your definitions after we begin the unit**. ====

//vertex// - Highest point
==== //x-intercept// - The point where the line crosses the x axis ==== ==== //y-intercept// - The point where the line crosses the y axis ==== ==== //increasing// - The y-value increases as the x-value increases. ==== //decreasing// - The y-value decreases  as the x-value increases. //maximum// - Highest point //minimum// - Lowest point //parabola// - A curved, U-shaped graph that represents a quadratic equation

==== **__ 5.2: __** **Summarize the similarities and differences between linear functions and quadratic functions. Discuss the graphs, the equations and the properties of each function.** ====

//Differences:// ==== linear functions describes a line i.e 3x+2=y. Graphing that equation would result in a line. An example of a quadratic equation is x^2+3x+1=y. Graphing this equation would give you a U shaped graph; a parabola. ====
