Objective: To compare properties of two functions represented in different ways
4-4 Comparing Functions (p.134)
SLOPE IS THE
RATE OF CHANGE!
b IS THE
INITIAL VALUE!
EX 1:
Which function has a greater rate of change?
Which function has a greater initial value?
EX 2:
y = 6x + 1
Which function has a greater rate of change?
Which function has a greater initial value?
Objective: To compare properties of two functions represented in different ways
When comparing initial costs, you might have to
solve for b using a set of points for x and y.

EX 5:
Amanda and Frank train for bicycle races. The graph at
the left represents the distance Amanda traveled during
Amanda's Distance today's training session. Frank's distance is given by the
function d = 18.5t, where d is the distance in miles and t
represents time in hours. Who traveled at the faster rate?
