Use function composition to determine if f(x) and g(x) are inverses. Answer yes or no. Hint - Find (fog)(x) and (gºf)(x).
1. f (x) = 3x + 5 and g(x) = 3x - 5
2. f(x) = 2x + 3 and g(x) = -2x - 3
3. f(x) = -4x + 16 and g(2) = 4 - 12
4. f (x) = 4+ $x and g(x) = x – 7

The volume, v, of a rectangular prism is determined using the formula, where / is the length, w is the width, and his theheight of the prism. carltren solves for w and writes the equivalent equation w=using this formula, what is the width of a rectangular prism that has a volume of 138.24 cubic inches, a height of 9.6 inches,and a length of 3.2 inches?
