The answer is : f(x) =3sin(2x+pi/2)

Explain

There 0,3 on the graph

You use this formula

f(x)=asin(kx-c)+h

and the maximum and minimum value of this function

a+ h and -a+ h

So a=3 and h=0

So we have

We have; f(x)= 3sin(kx - c)
and we have from the graph;

f(O)=3

So

Sin(-c) =-1

Therefore C=. Pi/ 2 +2pi n

We have period of the function is pi

2pi/ k
k=2
So it will equal Pi

Do you have any doubts ?

a bird of species a when diving can travel four times as fast as a bird of species b top speed if the total speeds of these two

weeeeeb [17]

X will be the speed of species b and 4x will be the speed of species a:

x + 4x = 180
5x = 180
x = 180 / 5
x = 36 m/h

If species b has a speed of 36 m/h, the speed of species a is 4 times that:

4 x 36 = 144 m/h.

Answer:

$\boxed {\bf A~=~36~m/h~and~B~=~144~m/h}$

Hope it helped,

Happy homework/ study/ exam!
