The pitch depends on the value of frequency. The frequency can be calculated using this formula:

Frequency = wave speed / wavelength

where wave speed = 343.00 m/s 
            wavelength = 0.77955 m

Frequency = 343.00 m/s / 0.77955 m
                   = 434.00 s^-1

Therefore the pitch is low since the frequency is also low.

ANSWER

The relation is not a function.

EXPLANATION

The relation is not a function because we have an x-coordinate mapping on to more than one y-coordinate.

This occurs at x=1.

The ordered pairs (1,1) and (1,3) disqualify the relation from being a function.

Hence the relation is not a function.
