Answer:
The vertex is y=-4
Step-by-step explanation:
The vertex is the minimum point of the graph of the quadratic equation.
Let's first find the like of symmetry.
dy/dx=2x+12
2x+12=0
2x=-12
x=-6
Now plug -6 into the quadratic equation
y=(-6)²+12(-6)+32
y=-4
You can just use the tn formula to solve this tn= t1 + (n-1)d
33% of decrease.
150-100=50
50 is 1/3 of 150
1/3= 33%
