Actually, I want to know the way of drawing such graphs in shortest time

Manish Shankar ·

like suppose I gave a graph of y=f(x)

how to draw y=f(|x|)
y=|f(x)|
|y|=f(x)
y=|f(|x|)| etc.

for y=(|x|) we will take only the positive x portionof y = f(x)

for y=|f(x)| we will take the positive part of y.

like this...

I do it in this way
for y=f(|x|) , forget about anything on the left hand side of the y-axis

take the image of the graph on positive side of y-axis in y-axis.

For y=|f(x)|, take the image of graph on negative side of x-axis in x-axis

For |y|=f(x), forget about anything on the bottom side of the x-axis

take the image of the graph on positive side of x-axis in x-axis.
