How long one can hold their breath can be calculated using the formula y=1.4g where y is the amount of time one can hold their breath in seconds and g is the size of their lungs in cubic centimeters.

Is this a relation or a function? Explain why.

Please Help!!
Thanks!!

    What is a function?

  • Math -

    A function is a relation between two sets in which one element of the second set is assigned to each element of the first set.

  • Math -

    so there is one and only one value of y for every value of g.
    therefore y is a function of g
