Question 880989: I have to write a comparison of these two periodic functions: f(x)= 3sin(piX/4)-2 and g(x)= -2sin(12piX/5)+7.
- I need to discuss amplitude - relate it to verticle dilation, verticle shift and its relationship to the line of equilibrium.
- mention any other transformations.
what i have figured out so far is that both have no phase shifts and both cross the line of equilibrium halfway between a peak and a trough. I'm just not sure if i'm right and haven't fully answer the question. I'll be really happy to get some help. thank you!
