1.1
Find an expression for the function whose graph is the line segment joining the points (
3,
-1) and (
7,
9). (Assume that these points are in the form (
x,
f(
x)).)
f(
x) =
1
,
2 
x 3

The graph of the function is given in blue. Use transformations to create the function whose graph is shown in red.
y =
8x −
x2
y =
1

(a) If
g(
x) =
2x +
1 and
h(
x) =
4x2 +
4x +
6, find a function
f such that
f 
g =
h. (Think about what operations you would have to perform on the formula for
g to end up with the formula for
h.)
f = 1
(b) If
f(
x) =
4x +
9 and
h(
x) =
4x2 +
4x +
5, find a function
g such that
f g =
h.
g(
x) = 2
