My rectangular soccer field site has a length equal to three times its width. find its area in terms of its length x.

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
