 * =quadratic: An equation who is squared and have the general form //ax2 + bx + c// =
 * ==vertex : is the central and the lowest of a quadratic function ==
 * ==x-intercept: f(x)=9x2+6x+5 you replace f(x) by 0 ==
 * ==y-intercept : it's the last number on a quadratic function 8x2+9x+4=0 or you can plus 0 for x f(0) ==
 * ==increasing: it's the x value in the vertex ==
 * ==decreasing: its the x-values in the vertex ==
 * ==maximum: is always at the vertex and it's when the y values is highest point at the vertex ==
 * ==minimum: is always at the vertex and its when the y values is lowest point at the vertex ==
 * ==parabola: A parabola is the shape of a quadratic equation. The vertex is curve. ==

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

= linear function: = = 7x - 2 is called a linear expression because its highest power is one,  is an equation between two linear expressions. line. = = = = quadratic function:degree of 2, axis of symmetry, graph is parabola, function notation f(x), = = =
