Ok so domain is all allowed numbers
look at deonomenator and don't allow any numbers that will make it zero
none
that means
domain=all real numbers
vertex
in form
y=a(x-h)^2+k
(h,k)=vertex
we have
y=-2(x+3)^2-1
h=-3
k=-1
vertex=(-3,-1)
range
the vertex opens down so max is y=-1
y≤-1
domain is all real
vertex is (-3,-1)
y≤-1
C
The pattern is if you write the alphabet backwards it is always going to be cross off two letters then skip a letter then cross off the letter after the letter that you skipped then skip two then cross off two letters
Answer:
Sample response: Determine what should go on each axis. Grades will go on the x-axis, and the number of students will be plotted on the y-axis. Find the number of different scores and range. Choose an interval – say, 10 percent. Find the frequency within each interval. Choose a scale – say, 0–3. Draw bars the height of the frequency for each interval.
Step-by-step explanation:
Idk.. If you divide 488 by 3 you will have your answer.
Its easy math.
Answer:1/15 or 0.06
Step-by-step explanation:
