Question 214933: The distance d (in miles) that a runner travels is given by the function d = 6t where t isthe time (in hours) spent running. The runner plans to run 12 miles. Using the graph ofthe function, identify its domain and range.
The domain is 0 ≤ t ≤ The range is 0 ≤ d ≤

You can put this solution on YOUR website!
Equation is:
d = 6*t
-----
To graph this equation, we let y = d and we let x = t
The equation becomes:
y = 6*x
----
The graph of this equation looks like:

-----
Since x cannot be negative, then your domain is 0 <= x < infinity
Your range will be 0 <= y < infinity
-----
x can go on forever in a positive direction and so can y.
neither x nor y can be negative.
