In this week, I learned how to graph the absolute value of quadratic equations. I concluded that we only need 3 steps to graph it:
-graph parent function
-find x-intercepts (critical point)
-graph (find all points below x-axis reflect them up)
Also I learned how to graph the reciprocals of quadratic functions.
-graph parent function
-find invariant points (y=1 or y=-1)
-find asymptotes (x=x-intercept and y=0)
-graph hyperbola
Ex: graph the absolute value of quadratic function
graph the reciprocals of quadratic function
In addition, the reciprocals of quadratic function have three extinct type
