In this unit we learned alot of new material some hard some easy. Like how to find the vertex of a parabola. First you graph the parabola on your calculator, then press 2nd trace, stroll down and selcect either minimum or maximum, now press enter and you should see it on your screen. ( Maximum=cap shaped, Minimum=Cup Shaped). We also learned types of functions.
x^1= Linear no curves, x^2= Quadractic 1 curve, x^3=Cubic 2 curves, x^4 =Quadratic 3 curves, and x^5 Quintic= 4 curves. We learned about Cubic functions, all cubic functions are in this form y=ax^3+bx^2+cx. Then we learned about domain and range I struggled with this part, Domain= X values and Range =y values. Type of vertex openings. a>0-opens upward,
a<0-opens>1-narrow parabola. Overall this unit was harder than the first unit for me.
