Suppose that f(x) and g(x) are functions on \(\mathbb{R}\) such that the range of f is [-5,3], and the range of g is [-2,1]. The range of f(x) * g(x) is [a, b]. What is the largest possible value of b?
The largest possible value of b is 3*1 = 3.
BBJJ sometimes the simplest answers are also the correct ones.
You can give back his/her point now and a show of appreciation would be good.
It's acually not correct...
Yes I see, you are correct, it is not right. the correct answer is equally simple though.
im not understand
-5*-2 = +10
That is the largest possible value.
+171
