A) We know that
where d
= distance,
v = velocity,
t = time
In this case, d = 2 mi., t = 30 min. So we get
Dividing both sides by 30, we get
Thus a function for his walk would be
where y = distance and x = number of minutes he walks.
b) Domain of a function is a set of x-values on which the function defined. In this case, the number of minutes is 30 at maximum. So the domain of the function is [0, 30].

so the 2nd equation is really the first equation in disguise.
since both equations are the same, that means if you graph them, is just one line pancaked over the other, and the solutions points is every single one on each, namely infinitely many solutions.
