How can you verify your x-intercept(s) are correct?]]> 2017-04-03 16:45:07 UTC https://padlet.com/thach_thao_phan/mpm2d_week9/wish/164403616 thach_thao_phan https://padlet.com/thach_thao_phan/mpm2d_week9/wish/164461144 Remember, when you square root something your answer should be positive or negative. This will help you find the x-intercepts, especially if there are 2 of them.]]> 2017-04-03 19:32:43 UTC https://padlet.com/thach_thao_phan/mpm2d_week9/wish/164461144 thach_thao_phan https://padlet.com/thach_thao_phan/mpm2d_week9/wish/164461721 This group had an idea of changing the equation to standard/y-intercept form. But it's not as easy as it looks! There's a very common error in the calculations of the equation on the top left. Do you see it?]]> 2017-04-03 19:34:36 UTC https://padlet.com/thach_thao_phan/mpm2d_week9/wish/164461721 thach_thao_phan https://padlet.com/thach_thao_phan/mpm2d_week9/wish/164665554 If you know the x-intercepts of a quadratic, then you can find the axis of symmetry by finding the midpoint (or average) of the x-intercepts. The axis of symmetry is the x-coordinate of the vertex, so all you need to find is the y-coordinate by using the equation.]]> 2017-04-04 16:30:35 UTC https://padlet.com/thach_thao_phan/mpm2d_week9/wish/164665554 thach_thao_phan https://padlet.com/thach_thao_phan/mpm2d_week9/wish/164973207 Here are the quadratic problems from today's class.]]> 2017-04-05 18:26:24 UTC https://padlet.com/thach_thao_phan/mpm2d_week9/wish/164973207 thach_thao_phan https://padlet.com/thach_thao_phan/mpm2d_week9/wish/164973908 This group completed the Dolphin question on the left side of the photo.]]> 2017-04-05 18:29:16 UTC https://padlet.com/thach_thao_phan/mpm2d_week9/wish/164973908 thach_thao_phan https://padlet.com/thach_thao_phan/mpm2d_week9/wish/165527536 2017-04-08 23:05:29 UTC https://padlet.com/thach_thao_phan/mpm2d_week9/wish/165527536 thach_thao_phan https://padlet.com/thach_thao_phan/mpm2d_week9/wish/165530414 2017-04-09 01:25:36 UTC https://padlet.com/thach_thao_phan/mpm2d_week9/wish/165530414 thach_thao_phan https://padlet.com/thach_thao_phan/mpm2d_week9/wish/165532116 Find the vertex from the equation y=-3(x+3)(x-1)]]> 2017-04-09 03:00:21 UTC https://padlet.com/thach_thao_phan/mpm2d_week9/wish/165532116 thach_thao_phan https://padlet.com/thach_thao_phan/mpm2d_week9/wish/165532213 The y-intercept and Vertex are the same point]]> 2017-04-09 03:06:30 UTC https://padlet.com/thach_thao_phan/mpm2d_week9/wish/165532213 thach_thao_phan https://padlet.com/thach_thao_phan/mpm2d_week9/wish/165532284 2017-04-09 03:10:17 UTC https://padlet.com/thach_thao_phan/mpm2d_week9/wish/165532284 thach_thao_phan https://padlet.com/thach_thao_phan/mpm2d_week9/wish/165532343 Can you find the equation of the quadratic with a vertex at (2,4) and y-intercept at (0,2)?]]> 2017-04-09 03:12:36 UTC https://padlet.com/thach_thao_phan/mpm2d_week9/wish/165532343 thach_thao_phan https://padlet.com/thach_thao_phan/mpm2d_week9/wish/165532414 Can you find the equation of the quadratic with x-intercepts at (-5,0) and (3,0) and another point at (-1,-4)?]]> 2017-04-09 03:15:12 UTC https://padlet.com/thach_thao_phan/mpm2d_week9/wish/165532414 thach_thao_phan https://padlet.com/thach_thao_phan/mpm2d_week9/wish/165532447 2017-04-09 03:17:00 UTC https://padlet.com/thach_thao_phan/mpm2d_week9/wish/165532447 thach_thao_phan https://padlet.com/thach_thao_phan/mpm2d_week9/wish/165532475 Can you find the perfect square in the following quadratic equations?
