Figure 1 below shows a sketch of y=g(x)y = g(x)y=g(x), where
g(x)={5−3xx<1(x−1)2+2x≥1g(x) = \begin{cases} 5 - 3x & x < 1 \\ (x - 1)^2 + 2 & x \geq 1 \end{cases}g(x)={5−3x(x−1)2+2x<1x≥1
Find the value of gg(0)gg(0)gg(0).
Using set notation, find all the values of x x\,x for which g(x)>18g(x) > 18g(x)>18.
