SP #2 Unit E Concept 7: Graphing polynomials, including, x and y-intercept, zeros(with multiplicities), end behavior.

     In concept 7, you'll be able to do a full evaluation of factorable polynomials and describe every aspect. The aspects are how the extremes behave, how the middle behaves, where the highest and lowest points are, where the intercepts are, and what intervals they are (increasing or decreasing).
     Pay attention in the multiplicity of zeros because its a big deal. if the multiplicity is 1 the graph goes through or if its 2 the graph bounces or if its 3 the graph curves. Each multiplicity represents a gate, so the graph can't go through unless there's a gate. To find the extremes you must use the graphing calculator using second calc.


SP #1 Unit E Concept 1: Identifying x and y-intercepts, vertex, axis of quadratics and graphing them.

     This concept will more into detail for graphing quadratics.in unit B, you only graph the quadratic using the shifts of the parent function. now you'll go a step further to make the graph more accurate and detailed by identifying the vertex, x and y-intercepts, and the axis of symmetry.
     Pay attention to start in standard form (f(x)=ax^2+bx+c) then complete the square to put the parent function form in f(x)=a(x-h)^2+k. The graph will include 2 to 4 points, those points will be the vertex, the x and y-intercepts, and the axis. To get the vertex its the (h,k) of the parent function, h will always be the opposite ex. h=2 it will be -2 for the vertex.
