1. Enter the amplitude of the function f(x) .

f(x)=−2sin(3x)−1

 

In the form  Asin (Bx) + C

The amplitude =  l A l   =  l -2 l  = 2

 

 

 

2. What is the equation of the midline for the function f(x) ?

 

f(x)=3cos(x)−2.5

 

Note that the max for the function is 3(1) - 2.5   =  0.5

And the min for the function is    3(-1) - 2.5 =  -5.5

 

To find the midiine.....add these values and divide the sum by 2

So we have

[ . 5  + - 5.5] / 2 =     -5/2 =  -2.5

 

So....the equation for the midline is   y = -2.5
