Graph   h(x)=7cos(12x)+1  . 

use 3.14 for π .

 

Graph   f(x)=3sin(12x)−5  . 

Use 3.14 for π.

OK.... due the the 12x  it will have 12 complete waveforms in a x distance of 2pi

 

The amplitude will be  '7'       or 14 from the top to the bottom of the wave

And finally the cos wave will be shifted UP by 1

 

I will post a pic in a sec

For the SECOND one you will also have 12 waveforms in 2 pi ...but it is a SIN wave

it will have an amplitude of 3  (6 units from peak to low point)   and it will be shifted DOWN by 5 units....

Cool?
