For the family of quadratic functions, y = ax2 + bx + c, the most basic functionof this kind is y = x2.

The "parent" parabola can give birth to a myriad of other parabolic shapes through the procedure of transformations. Brush off your memories that transformations and also let"s take a quick look in ~ what is possible. When graphing quadratic features (parabolas), store in mind that two creates of equations may be used: move the graph vertically - up or down y = x2+ k move the graph increase 4 devices y = x2+ 4 moves the graph down 4 devices y = x2- 4move the graph horizontally - left or right y = (x - h)2 y = (x - 4)2 move the graph best 4 units )y = (x + 22moves the graph LEFT 2 systems flip the graph over the x-axis (negates the y-values of the coordinates)y = -(x2) parental graph y = x2 parent reflected end y = -(x2)x-axis flip the graph over the y-axis (negates the x-values that the coordinates) y = (-x)2 parent graph y = x2 parental reflected end y = (-x)2y-axis stretches away from the x-axis or compresses toward the x-axis y = a • x2 | a | > 1 is a stretch; 0 parental graph y = x22 upright compression y = ¼(x)2 upright stretch y = 4(x)See more: How Many Cm Are In 3/4 Of An Inch Es To Mm, How Many Cm Are In 3/4 Inch stretches far from the y-axis or compresses toward the y-axis y = (a • x)2 | a | > 1 is a compression by element of 1/a; 0 parent graph y = x2y = (¼x)2 horizontal stretch y = (4x)2 horizontal compression Topical overview | Algebra 1 synopsis | chrischona2015.org | MathBits" Teacher resources Terms the Use |
