The coefficients a,b, and c can show properties of the graph of the function. ]]> 2016-02-22 17:56:31 UTC https://padlet.com/10011094/auqhaxbgqczl/wish/96507025 10011094 https://padlet.com/10011094/auqhaxbgqczl/wish/96509199 Example of how to find the axis of symmetry in a graphing quadratic function in Standard Form]]> 2016-02-22 18:01:54 UTC https://padlet.com/10011094/auqhaxbgqczl/wish/96509199 10011094 https://padlet.com/10011094/auqhaxbgqczl/wish/96513545 2016-02-22 18:12:58 UTC https://padlet.com/10011094/auqhaxbgqczl/wish/96513545 https://padlet.com/10011094/auqhaxbgqczl/wish/96516595 2016-02-22 18:21:20 UTC https://padlet.com/10011094/auqhaxbgqczl/wish/96516595 Step A the function f(x)=x^2-4x+6 https://padlet.com/10011094/auqhaxbgqczl/wish/96517963 a. Determine whether the graph opens upward or downward.

b. Find the axis of symmetry
The axis of symmetry is given by x= -b/2a

c. Find the vertex. The vertex lies on the axis of symmetry, so the x-coordinate is 2. The y-coordinate is the value of the function at this x-value, or f(2).
f(2)=(2)^2-4(2)+6=2


d. Find the y-intercept
Because c=6, the y intercept is 6.

e. Graph the function
Graph by sketching the axis of symmetry and then plotting the vertex and the intercept point,(0,6). Use the axis of symmetry to find another point on the parabola.  ]]> 2016-02-22 18:25:14 UTC https://padlet.com/10011094/auqhaxbgqczl/wish/96517963 10011094 https://padlet.com/10011094/auqhaxbgqczl/wish/96521641 2016-02-22 18:35:05 UTC https://padlet.com/10011094/auqhaxbgqczl/wish/96521641 10011094 https://padlet.com/10011094/auqhaxbgqczl/wish/96522242 2016-02-22 18:36:29 UTC https://padlet.com/10011094/auqhaxbgqczl/wish/96522242 Step B consider the function f(x)=-4x^2-12x-3 https://padlet.com/10011094/auqhaxbgqczl/wish/96523010 a.
