b)
order of transformations:
1 - dilation by a factor of $\frac{3}{5}$ from the x axis (vertical). $h(x) \to \frac{3}{5}h(x)$
2 - translation one unit in the positive y direction (vertical). $\frac{3}{5}h(x) \to \frac{3}{5}h(x) + 1$
3 - translation two units in the negative x direction (horizontal). $\frac{3}{5}h(x) + 1 \to \frac{3}{5}h(x + 2) + 1$
4 - reflection in the y axis (horizontal). $\frac{3}{5}h(x) + 1 \to \frac{3}{5}h(-x + 2) + 1$
5 - dilation by a factor of $\frac{1}{3}$ from the y axis (horizontal). $\frac{3}{5}h(-x + 2) + 1 \to \frac{3}{5}h(-3x + 2) + 1$

$g(x) = \frac{3}{5}h(2-3x) + 1 = \frac{3}{5}\times \frac{1}{2-3x} + 1 = \frac{-3}{5(3x-2)} + 1$
