Motivational Monday!
Check Homework from Thursday Night
Graphs of quadratics are called The vertex is or Graphing Quadratics Graphs of quadratics are called The vertex is or Point: parabolas maximum minimum (-2, -3)
Graphing Quadratics The axis of symmetry is the Line that the parabola into two matching halves. Line: divides x = -2
The Parent Graph for the quadratic function is Let’s see what transformations happen when we change part of that equation... y = x2
Changing the constant causes a shift of the parabola, aka Translation vertical
Changing the constant causes a shift of the parabola, aka Dilation narrower
Changing the constant causes a shift of the parabola, aka Reflection Open down or flip

Whodunnit? Six contestants on a reality TV show were stunned to find their lowest scoring colleague was “murdered”. They must figured out the crime before the bell rings. The question is Whodunnit? And how...The Player, Last Known Whereabouts and Method that are left unaccounted for --is the solution.

GCF stands for greatest common factor. Find the GCF of the following: Factoring Method 1: GCF GCF stands for greatest common factor. Find the GCF of the following:
Example 1: Factor the following Factoring Method 1: GCF When we factor, we want two linear terms (no x squared). Sometimes, all we need to do it take out a GCF. Example 1: Factor the following
Example 2: Factor the following Factoring Method 1: GCF Example 2: Factor the following Example 3: Factor the following
You try! Factor the following Factoring Method 1: GCF You try! Factor the following You try! Factor the following
Factoring Method 2: Factor by grouping Works when there are 4 terms in the polynomial in descending degree order. Split the polynomial into two sets of two terms Factor each set separately (factor out GCF) Factor out common polynomial
Factoring Method 2: Factor by grouping Example 1: Factor the following Example 2: Factor the following
Factoring Method 2: Factor by grouping You try! Factor the following You try! Factor the following
No Homework Happy Pi Day!!!!
