We have that
f(x)=(x-4)^2-1 in the question and f(x)=-(x-4)^2-1 in the picture
<span>so
</span><span>I'm going to analyze the two cases
</span><span>
using a graph tool
case 1)
</span>f(x)=(x-4)^2-1<span>
the vertex is the point (4,-1)
the x intercepts are the points (3,0) and (5,0)
the y intercept is the point (0,15)
</span><span>the axis of symmetry is x=4
</span>see the attached figure N 1
case 2)
f(x)=-(x-4)^2-1
the vertex is the point (4,-1)
there is no x intercepts
the y intercept is the point (0,-17)
the axis of symmetry is x=4
see the attached figure N 2
the answer <span>
considering the case N 2 </span>
isvertex (4,-1)------> is correcty intercept (0,-17)-----> is correctaxis of symmetry x=4-----> is correct
Answer:
h is a function
Step-by-step explanation:i know that h is a function i just dont know why
The order of the 3 books does not matter so its the number of combinations of 3 from 45
b is the correct choice
Answer:
I don't know that options but......
if we are rounding to the thousands, then the answer would be 3,000
if hundreds, the answer is 3,400
if tens: 3,390
If ones: 3,390
Step-by-step explanation:
round each number up or down based upon what the digit is.

First look at the difference of the items sold between the 2 people. Clearly Lizzie sold 9 more boxes of peaches and earned 162 more dollars. We can solve and get that each box of peaches are worth 18 dollars. Then use what we found out --> 4 boxes of apples+1 boxes of peaches = 54 dollars. so 4 boxes of apples are worth 54-18=36 dollars. and thus each box of apples are worth 9 dollars.
Answer: each box of apples are wroth 9 dollars and each box of peaches are wroth 18 dollars. Done!
