Well have you found the max values of both functions?

f is already in vertex form

no i havent.

And for g you just have to look for which g(x) value is the highest and that is the max

I am very confused i am just learning this stuff.

everything is lined up where it should be
a is -5
h is 0
k is...

9?

yes

now followed what I said above

since a is negative then k is a max

you did have a is -5
so k=9 is your max

9 is the max value of f

can you look at your list of g(x) values and just say what the highest number is listed there

8?

yes so the max of g is 8

are you able to answer the question now?

SO the answer is c?

so you think 9 is 3 units less than 8?

OH

Its D.

yes 9 is one more than 8

Can you help with 1 more?

I can try

let me get the graph

ok so the area of that whole thing given is 7 ft^2

|dw:1440176151768:dw|
what is the height of the rectangle?

I put black boxes around the numbers you might think interesting when answering that question

So the answer is A.

Did you want to try to figure out the height of the rectangle?

Or did you want to guess at the choices of your question?

please don't be rude. I thought that was the answer.

I wasn't being rude. You were ignoring my question.

I was not.

but you never answered my question...

Its 2x^2

the total height is x+2+x or 2x+2 |dw:1440176571442:dw|

can you find the base length of the rectangle

|dw:1440176598630:dw|

3x?
