Answer 11

Hmmm, looks like for one of the functions, the y values are all negative.

Answer 12

True, but I need to know which function has the greatest maximum y-value. Can you help me with that? @Hero

Answer 13

By default, you can eliminate h(x) since its y values are all negative. So, now it's basically between f(x) and g(x).

Answer 14

Here's what you should observe about g(x). It's maximum value is only 3. Nevertheless I will ask you this: for f(x), what is the result when x = 0?

Answer 15

give me a sec, let me do the problem

Answer 16

That's the spirit!

Answer 17

I got 2.99

Answer 18

So for f(x) = 3*cos(2x) + 4 when you enter 0 for x which results in
f(0) = 3*cos(2(0)) + 4, the result you get is 2.99?

Answer 19

Wait... Actually it's 7, I did something wrong the first time I tried to solve it

Answer 20

So the answer is f(x) right? Thank you so much :)

Answer 21

Correct. So looks to me like in terms of max values f(x) > g(x) > h(x)

Answer 22

Thanks :) Can you help me with another one?

Answer 23

Wbu? @RhondaSommer can you help me with another one?

Answer 24

Oh yay you're back :) @Hero
