What is the vertex of the graph of y = −1(x − 2)2 + 3
Alona [7]

Vertex: \ (2,3)

<h2>Explanation:</h2>

The vertex form of the equation of a parabola is given by the following form:

f(x)=a(x-h)^2+k \\ \\ Where: \\ \\ a:Leading \ Coefficient \\ \\ (h,k):Vertex \ of \ the \ parabola

In this exercise, we have the following equation:

y=-(x-2)^2+3

From here, we can conclude that:

Leading \ coefficient: \ -1 \\ \\ Vertex: \ (2,3)

Since the leading coefficient is less than zero, the parabola open downward. So, the graph is shown below and the vertex has been indicated.

I really need help, will give brainliest
Annette [7]
Here’s how it’s done: you count the total number of m&ms to start.
then, you count the number of each color of m&ms. i’m just making up numbers right now but say there are 50 m&ms total and 10 of them are blue. you would put the number of blue m&ms over the total number of m&ms. this would make the probability you pull a blue m&m 10/50. you would then simplify the answer to 1/5. that would be what u put in the box. remember, i just made up those numbers so that’s not the real answer but hopefully u get the point haha. if ur still confused ask me
