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

do you know what the biggest cosine can be?

2 years ago
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?

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)
