SAMPLE QUESTION Use the function below to answer the following questions. x
f x =3 +4 (a) Use transformations of the graph of
y=3
x
to graph the given function.
(b) Write the domain and range in interval notation. (c) Write an equation of the asymptote. EXPLANATION
(a) Use transformations of the graph of
y=3
x
to graph the given function.
x
f x =3 +4 The graph of
f is the graph of the parent function y = 3

4units upward.
x The parent function y = 3 is an increasing exponential function. We can plot a few points on the graph of and use these points and the horizontal asymptote to form the outline of the transformed graph.
