Suppose a function f(x) is defined on the domain [-8,4] . If we define a new function g(x)

by g(x) = f(-2x), then what is the domain of g(x)? Express your answer in interval notation.

\(-8\le -2x \le 4\\ -8\le -2x\qquad and \qquad -2x \le 4\\ \quad 4\ge x\qquad \quad and \qquad \qquad  x \ge -2\\ \quad x \le 4\qquad \quad and \qquad \qquad  x \ge -2\\ -2 \le x \le 4\)'

 

domain is

[-2,4]
