URGENT!! NEED HELP ASAP!!!
WILL FAN AND MEDAL IF YOU HELP


Compare the functions shown below:


f(x)

cosine graph with points at 0, negative 1 and pi over 2, 1 and pi, 3 and 3 pi over 2, 1 and 2 pi, negative 1
g(x)

x y
−6 −11
−5 −6
−4 −3
−3 −2
−2 −3
−1 −6
0 −11
h(x) = 2 cos x + 1


Which function has the greatest maximum y-value?

Answer 9

here is the graph of h(x):

Answer 10

so, you have to compare these values:
minimum value of f(x), minimum value of g(x), and minimum value of h(x)

Answer 11

hint:
the minimum value of g(x) is -11

Answer 12

so the max for g(x) is -2

Answer 13

yes!

Answer 14

for f(x) it's 3 and g(x) 3?

Answer 15

the minimum value of f(x) is -1, and the minimum value of h(x) is also -1

Answer 16

Oh ok, the question is asking for max value though

Answer 17

In that case, we have:
max value of f(x)=3
max value of g(x) = -2
max value of h(x)= 3

Answer 18

so the answer would be d, f(x) and h(x)

Answer 19

yes! correct!
