Evaluate Functions Using a Graph

Using the graph, find the average rate of change at which this person was traveling. 

• 80 miles per hour

• 40 miles per hour

• 20 miles per hour

• 160 miles per hour

Which line has the greatest average rate of change on the graph? Why?

• Blue, it's average rate of change is $120 per month

• Red, it's average rate of change is $40 per month

• Blue, it's average rate of change is $160 per month

• Red, it's average rate of change is $80 per month

What is the domain of the pictured graph?

Which piecewise function corresponds to this graph? (Take your time)

• f(x) = { x  if x < 4;   -x+1  if x ≥ 4

• f(x) = { x  if x ≤ 4;  -x+1  if x > 4

• f(x) = { -x+1  if x < 4;  x  if x ≥ 4

• f(x) = { -x+1  if x ≤ 4;  x if x > 4
