# Transformation
+**Order of operations:** DRT - Dilations, Reflections, Translations
+
## $f(x) = x^n$ to $f(x)=a(x-h)^n+K$##
- $|a|$ is the dilation factor of $|a|$ units parallel to $y$-axis or from $x$-axis
2. - Dilating from $y$-axis: $(x, y) \rightarrow (ax, y)$
- Replacing $x$ with $x \over a$ to obtain $y = f({x \over a})$
-For graph of $y={1 \over x}$, horizontal & vertical dilations are equivalent (symmetrical). If $y={a \over x}$, graph is contracted rather than dilated.

+## Transformations from $f(x)$ to $y=Af[n(x+c)]+b$#
+
+Applies to exponential, log, trig, power, polynomial functions.
+Functions must be written in form $y=Af[n(x+c)] + b$
+
+$A$ - dilation by factor $A$ from $x$-axis (if $A<0$, reflection across $y$-axis)
+$n$ - dilation by factor $1 \over n$ from $y$-axis (if $n<0$, reflection across $x$-axis)
+$c$ - translation from $y$-axis ($x$-shift)
+$b$ - translation from $x$-axis ($y$-shift)
