Answer (-3,6)
#
f(x)=x ² +6x+15
=(x ² +6x+9)+6
=(x+3) ²+6
the vertex:(-3,6)
The step function is characteristic of the floor or ceiling functions, which map a real number to an integer. There's clearly a factor of 2, indicated by two units of y for every one unit of x.
The open and filled circles indicate, for example, f(1)=2, f(1.01)=4. That means we're rounding up, so we're using the ceiling function.

Answer: second choice
Answer:
Step-by-step explanation:
By inscribed angle theorem:

I don't know how to get the answer, but i know the answer is 127.50.
Hey there Caleb!
To start of, the sentence was clear on that it said . . .

The statement listed above is the (key) point. We need to keep this in mind.
So, now that we know this.
We would use the mathematic (Ф)
So,sense we know that a (hexagon) had it's (6) shapes, we would do
. . .
Ф = 360° : 6 = 60°
Your correct answer to this question would be
. . .

Hope this helps.
