Transformations of Graphs [A*]

Transforming a graph is about changing a function in a particular and
predictable way.

For clarity all the functions are referred to as f(x). All this means is `any
function where the only variable is x'

For example:
f(x) = x + 3
f(x) = 5x…

Y = x2

Y = (x + 2)2

















Y = x2

Y= 2x2

Y = sin x Y = sin (2x)








Y= x2 + 2x ­ 1

Y = -x2 ­ 2x +1















Y = x2 + 2x

Y = (-x)2 +2(-x)

Example #1: The following is the graph for Y = x2 + 3x ­ 4. On the same
axes draw the graph Y = 2x2 + 3x ­ 2. Describe the transformations.
