Question

what effect does a positive amplitude and a negative amplitude have?

Answer 1

amplitude, in periodic functions; provides bounds that the function oscilates in

Answer 2

what type of reflection is a negative amplitude?

Answer 3

a negative ... amplitude, i assume reflects about the x axis if using the conventional xy axis construction

Answer 4

if y= sin(x) then the graph of y=-sin(x) is reflected about the x axis

Answer 5

if y = x^2; then y=-x^2 is reflected about the xaxis

Answer 6

got it! thanks
