Checkin: Draw/write - What is one thing that you did over Spring Break?
Which is a Standard Form Equation of a Quadratic Function?
- y=a(x-r1)(x-r2)
- y=ax^2+bx+c
- y=a(x-h)^2+k
What is the formula to help you find the x-coordinate of the Vertex from a Standard Form equation? Write it below.
- x=-b/2a
- x=(r1-r2)/2
- x=(h,k)
After using the formula, what do we do to find the rest of the vertex (the y-value)
- Use the Quadratic Formula
- Plug the x-value into the original equation
- Factor the equation to find the answers
Standard Form helps you find which point the easiest?
- x-intercept
- Vertex
- y-intercept
Which coefficient from the standard form equation helps you find what you said in the question #4?
Draw a rocket ship going to the moon with an alien driving it.
Do you like these little brain breaks during lessons?
- Yes, let's do it again sometime!
- No, I would prefer not to do it again...
