Lecture 14 Page 1
Suppose you have a function y = f(x) such that the domain of f(x) is 2 ≤ x ≤ 7and the range of f(x) is −10 ≤ y ≤ 50.
Find constants B and C so that the domain of f(B(x − C)) is 8 ≤ x ≤ 9.a)Find constants A and D so that the range of Af(x) + D is 0≤ y ≤ 2.b)
Question similar to Ch 8 #6 (or textbook 8.8)

Recall: A FUNCTION f(x) is a rule that maps each element in the domain D to one and only one element in the range R.
