I really need help with math question i will give a medal!!!!

OpenStudy (anonymous):

f(x) g(x) g(x) and h(x) f(x) and h(x)

OpenStudy (anonymous):

what's the question?

OpenStudy (xapproachesinfinity):

like @peachpi said i don;t see any question all i'm seeing is the givens

OpenStudy (anonymous):

which function has the greatest maximum y-value?

OpenStudy (anonymous):

sorry thats the question @peachpi @xapproachesinfinity

OpenStudy (anonymous):

you can see the maximum value of \(f\) from the graph, the highest point on the graph is ___

OpenStudy (anonymous):

3, pi

OpenStudy (anonymous):

other way around. it's (π, 3)

OpenStudy (anonymous):

right sorry

OpenStudy (anonymous):

But what you're interested in is the y-value, 3

OpenStudy (anonymous):

actually it is none of those it is \(3\) as @peachpi said it is a number, not a point

OpenStudy (anonymous):

ohhh ok what do i do with it?

OpenStudy (anonymous):

For g you pick the highest y from the table

OpenStudy (anonymous):

hold that thought, and find the maximum of \[2\cos(x)+1\]

OpenStudy (anonymous):

i dont know what to do with that

OpenStudy (anonymous):

do you know what the biggest cosine can be?

OpenStudy (anonymous):

no i dont

OpenStudy (anonymous):

hmmm the biggest cosine can be is 1 (the smallest is -1)

OpenStudy (anonymous):

oh so what do i do with that information?

OpenStudy (anonymous):

that means the biggest \(2\cos(x)\) can be is \(2\times1=2 \) and therefore the biggest \(2\cos(x)+1\) can be is \(2+1=3\)

OpenStudy (anonymous):

so it would be D sence both are the same right?

OpenStudy (anonymous):

idk what is D?

OpenStudy (anonymous):

f(x) and h(x)

OpenStudy (anonymous):

ok yeah D

OpenStudy (anonymous):

yay thank you! i gave you your medal!
