3. Graphs and transformations Flashcards
constant function
f(x)=c
identity function
f(x)=x
quadratic functions
when and how positive?
reciprocal function
cubic function
asymptote
values approach, but never reach
positive square root function
translation
the graph moves along y or x axis
transformation
the shape of the graph changes. it stretches or squashes
f(x) − c:
The graph of f(x) is translated by c units in the -y direction.
f(x) + c:
The graph of f(x) is translated by c units in the positive +y direction.
f(x + c):
The graph of f(x) is translated by c units in the -x direction.
f(x − c):
The graph of f(x) is translated by c units in the +x direction.
cf(x), c > 0:
The graph of f(x) is stretched by a factor of c in the +y direction, about the x-axis.

f(cx), c > 0:
The by a factor of 1/c in the +x direction, about the y-axis
