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

anonymous · Answer

what's the question?

xapproachesinfinity · Answer

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

anonymous · Answer

which function has the greatest maximum y-value?

anonymous · Answer

sorry thats the question @peachpi @xapproachesinfinity

anonymous · Answer

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

anonymous · Answer

3, pi

anonymous · Answer

other way around. it's (π, 3)

anonymous · Answer

right sorry

anonymous · Answer

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

anonymous · Answer

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

anonymous · Answer

ohhh ok what do i do with it?

anonymous · Answer

For g you pick the highest y from the table

anonymous · Answer

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

anonymous · Answer

i dont know what to do with that

anonymous · Answer

do you know what the biggest cosine can be?

anonymous · Answer

no i dont

anonymous · Answer

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

anonymous · Answer

oh so what do i do with that information?

anonymous · Answer

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

anonymous · Answer

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

anonymous · Answer

idk what is D?

anonymous · Answer

f(x) and h(x)

anonymous · Answer

ok yeah D

anonymous · Answer

yay thank you! i gave you your medal!
