Josh mows grass to earn extra money. He charges $25.00 for each lawn. He mows at least 5 yards each week; but not more than 20 yards. The function f(x) = 25x models his income. Write the domain of the function as an inequality.
F(x)=25X Domain {5<=x ERlx<=20} In words: Set of x that are members of the real numbers such that x greater than or equal to 5 but less than or equal to 20. I cannot write the exact mathematical symbols here but I have translated it into words.
