The following function is defined by two equations. The equation in the first row gives the output for values of $x$ less than 4. The equation in the second row gives the ouput for values of $x$ which are greater or equal to 4. $$h(x) = \begin{cases}\displaystyle{2x+4}&\text{if}\ x < 4\cr \displaystyle{2x-5}&\text{if}\ x \ge 4\end{cases}$$ Find the indicated values:

a) $h(4)$ =

b) $h(1)$ =

c) $h(5)$ =
