Graph of f(x) is given. Draw the graph of [f(x)]
We want to draw [f(x)]. Mark the integer points on y-axis. Between any two integers, pull the graph
down on the smaller integer.
So the graph of [f(x)] will look like in option D
How does the graph of f(2x) look like if the graph of f(x) is
Graph of f(x) is given. Draw the graph of f−1(x)
