For what values can t take?
Or maybe it might be eaiser to ask yourself are there any values t cannot take?
Im in high school and im having real bad trouble with this math question.. Its finite math and im learning about linear equations.
Right now im learning about f(x) equations..
I just wanted to see if any of you knew how i would go about this question? Im not sure how to find the domain, heres the question:
"A certain pollutant is being removed from a small lake. Let t be the number of days from the beginning of the removal process and
f(t)= 50(1 - t/120) be the number of parts per million of this pollutant in the water. Find the domain of the function and sketch its graph throughout the domain."
