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

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 ___

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

2 years ago
OpenStudy (anonymous):

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

ohhh ok what do i do with it?

OpenStudy (anonymous):

For g you pick the highest y from the table

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

i dont know what to do with that

do you know what the biggest cosine can be?

2 years ago
OpenStudy (anonymous):

no i dont

2 years ago
OpenStudy (anonymous):

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

2 years ago
OpenStudy (anonymous):

oh so what do i do with that information?

2 years ago
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?

2 years ago
OpenStudy (anonymous):

idk what is D?

2 years ago
OpenStudy (anonymous):

f(x) and h(x)

2 years ago
OpenStudy (anonymous):

ok yeah D
