Expert Solution
Step 1: Given details about Transformation Rules

Here are some rules to transform the given graph of function.

f(x + a) horizontally shift the graph of f(x)left by a units

f(x - a) horizontally shift the graph of f(x) right by a units

f(x)+ a vertically shift the graph of f(x) upward by a units

f(x)- a vertically shift the graph of f(x) downwards by a units

af(x) vertically stretches the graph of f(x) by a factor of a units

1/a f(x) vertically shrink the graph of f(x) by a factor of a units

f(ax) horizontally shrink the graph of f(x) by a factor of a units

f(x/a) horizontally stretch the graph of f(x)by a factor of a units

-f(x) represents the reflection of the graph of f(x) over the x axis.

f(-x) represents the reflection of the graph of f(x) over the y axis
