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

1.3
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
