consider the exponential function f(x) = 3 and its graph. which statements are true for this function and graph? check all that apply.

the initial value of the function is 1/3
the growth value of the function is 1/3
the function shows exponential decay.
the function is a stretch of the function f(x) = (1/3)x .
the function is a shrink of the function f(x) = 3x.
one point on the graph is (3, 0).

The blue whale is the largest animal living on the earth. the average blue whale measures 100 feet long (30 meters) and weighs 300,000 pounds (136,000 kilograms). a whale’s head is 1⁄3 of the length of its body. a new baby whale is 1⁄4 the length of a grown whale. the average man is 1⁄17 the length of a blue whale, and 1⁄1,818 its weight. a human baby measures 1⁄4 of the length of an adult. calculate the following information: how long is a whale’s head? how long is a new baby whale? how tall is the average man? how much does the average man weigh? how tall is the average human baby?

The tuition costs, c, for a local community college are modeled by c(h) = 250 + 200h, where h represents the number of credit hours taken. the local state university has tuition costs, s, modeled by the function s(h) = 300 + 180h. how many credit hours will a student have to take for the two tuition costs to be equal? round the answer to the nearest tenth of an hour.

Which number line represents the solution set for the inequality -1/2x> 24?
