Answer: Choice B
y = (x+3)^2 - 1
==================================================
Recall that vertex form is y = a(x-h)^2 + k with the vertex being (h,k)
From the given graph, it shows that (h,k) = (-3,1) is the vertex. So we plug this pair of values into the general function above to get
y = a(x-h)^2 + k
y = 1(x-(-3))^2 + (-1)
y = (x+3)^2 - 1
which is the final answer
note: a = 1 is the case for all four answer choices, so we don't have to worry about the value of 'a'

i hope u find ur answer
Answer:
Step-by-step explanation:
The easiest way to do this is to assume you don't get a 1 or 2. You make your first draw from 8.
8 * 7 * 6 * 5 = 1680
The total number of ways of drawing 4 marbles is
10*9 * 8 * 7 = 5040
P(`(1 or 2) ) = 1680 / 5040 = 0.33333
The probability of getting a 1 or 2 in 4 throws = 1 - 0.3333 = 0.66667
The answer is 1/3. I hope I’m not late but I just saw this
Give more context please??
