The domain of $y=g(x)$ is $-7 \leq x \leq 22$ and the range is $-18 \leq y \leq 16$. Give both the domain and range of the following two functions as inequalities.

(a) $\displaystyle y = g \left( \frac{1}{4} x \right)$ has

Domain: help (inequalities)
Range:   help (inequalities)

(b) $\displaystyle y = 3 g (x)$ has

Domain: help (inequalities)
Range:   help (inequalities)
