For each pair of functions $f$ and $g$ below, find $f(g(x))$ and $g(f(x))$. Then, determine whether $f$ and $g$ are inverses of each other. Simplify your answers as much as possible. (Assume that your expressions are defined for all $x$ in the domain of the composition. You do not have to indicate the domain.) (a) $f(x) = \frac{x+7}{2}$ $g(x) = 2x - 7$ $f(g(x)) = \square$ $g(f(x)) = \square$ $\circ f$ and $g$ are inverses of each other $\circ f$ and $g$ are not inverses of each other (b) $f(x) = 3x$ $g(x) = 3x$ $f(g(x)) = \square$ $g(f(x)) = \square$ $\circ f$ and $g$ are inverses of each other $\circ f$ and $g$ are not inverses of each other

(The Fan class) Design a class named Fan to represent a fan. The class contains: Three constants named SLOW, MEDIUM, and FAST with the values 1, 2, and 3 to denote the fan speed. A private int data field named speed that specifies the speed of the fan. A private bool data field named on that specifies whether the fan is on (the default is False). A private float data field named radius that specifies the radius of the fan. A private string data field named color that specifies the color of the fan. The accessor and mutator methods for all four data fields. A constructor that creates a fan with the specified speed (default SLOW), radius (default 5), color (default blue), and on (default False).
