The horizontal axis ranges from start fraction negative pi over 4 end fraction to start fraction pi over 4 end fraction. The vertical axis ranges from negative 1 to 1 in increments of 1. The waveform passes through the following coordinates left parenthesis start fraction negative pi over 4 end fraction comma 1 right parenthesis, left parenthesis start fraction negative 3 pi over 16 end fraction comma 0 right parenthesis, left parenthesis start fraction negative pi over 8 end fraction comma negative 1 right parenthesis, left parenthesis start fraction negative pi over 16 end fraction comma 0 right parenthesis, left parenthesis 0 comma 1 right parenthesis, left parenthesis start fraction pi over 16 end fraction comma 0 right parenthesis, left parenthesis start fraction pi over 8 end fraction comma negative 1 right parenthesis, left parenthesis start fraction 3 pi over 16 end fraction comma 0 right parenthesis, and left parenthesis start fraction pi over 4 end fraction comma 1 right parenthesis.

f(x) = cos(8x)
Reason: cos(8x) has value 1 at x=0, zeros at x = ±π/16, minima −1 at x = ±π/8, and repeats with endpoints at ±π/4, matching the given points.
