12. [tex]h(x) = (x+4)^2[/tex]
The parent function is [tex]h(x)=x^2[/tex].
This graph is translated 4 units to the left of vertex of the parent function.
16. [tex]g(x)= -x[/tex]
Parent function y= x
Transformation: the graph g(x) is reflected about y- axis.
18. f(x)= -2
Parent function y= 2
Transformation - Reflection about x- axis.
20. g(X) = 4x
Parent function : y= x
Transformation: Vertical stretch/ compression.
