The speed of sound depends on the ambient air temperature. The formula that relates air temperature T {degrees Celsius) to the speed of sound v {meters/second) is given by: v =331.3, 1+ 273.15 a) Use technology to graph this function. {Note: v is the dependent variable and T the independent variable.] Sketch the graph below. {You are free to use Desmos, a graphing calculator, wolframalpha.com, etc.} b) State the functions domain {T}: c) State the functions range {v}: d) Determine the speed of sound to the nearest m/s at a temperature of 40 C.
