Step by step solution

01

Step 1. Given Information

The given figure is

02

Step 2. Explanation

On a touch-tone phone, each button produce a unique sound and the sound produced is the sum of two tones.

For the button key *, the low frequency is 941 cycles per second and high is 1209 cycles per second.

Thus, the sound emitted by touching * is given by,

y=sin(2蟺濒迟)+sin(2蟺丑迟)y=sin(2蟺(941)t)+sin(2蟺(1209)t)y=sin(1882蟺迟)+sin(2418蟺迟)

Thus, the graph of the obtained function is
