week 12-Linear Inequalities
The parabolic opening upward and equation is greater than zero. The equation has an intersection with the x axis. If the y value is greater than 0 x the value is less than one half and x is greater than… Continue Reading
Week8—Analyzing Quadratic functions of the form y=a(x-p)^2+q
y=x^2+2 positive sign the graph moves up y=x^2-3 negative sign the graph moves down y=(x-2)^2 negative sign the graph moves right y=(x+3)^2 positive sign the graph moves Left
Week 9—Graphing a Quadratic function
The basic representation of the quadratic function is y=ax squared +bx+c (a is not 0). The second function must be quadratic, and the graph of the quadratic function is a parabola that is parallel to the Y-axis or overlaps on… Continue Reading
