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
