the equation is L = 3D + 200
D is the number of days
L is the lengh of the road
D is from 0 to 70.
this makes L from 200 to 410 because 3 * 70 = 210 + 200 = 410.
D is in the domain
L is in the range.
if you graphed this equation, you would get the following.
in the graph, y takes the place of L and x takes the place of D.
the domain is the value of x from 0 to 70.
the range is the value of y from 200k to 410.
translate to L and D to get:
the domain is the value of D from 0 to 70.
the range is the value of L from 200 to 410.
what is the fallacy in this equation?
if the crew works zero days, 200 miles of the road is still built.
but, that's not a consideration here.
the only consideration is what is the domain and what is he range.
based on the information provided, your answer is corect.
