Answer: B
Step-by-step explanation:
If you begin with the basic equation of a vertical parabola: y-k=a(x-h)^2, where (h,k) is the vertex, then that equation, when the vertex is (-3,-2), is
y + 2 = a (x + 3)^2. If we solve this for y, we get
y = a(x+3)^2 - 2. Thus, eliminate answers A and D. That leaves B, since B correctly shows (x+3)^2.
Answer:
a) XT
c)ZS
I don't know of the b one
Multiply base time height. Simply put B(H)=A
B=3 1/2
H=2 2/3
A=(3 1/2)(2 2/3)
A=28/3
A=9.3333
