Find the Function Rule
The bus driver drives 150 miles every day on his
route. Find the function rule. Then make a
function table to find how many miles he drives in
3, 4, and 5 days.
The output value is 150 times the input value.
Find the Function Rule

150 × 4
600
5
150 × 5
750
Answer: So, the number of miles driven is 450, 600,
and 750 for 3, 4, and 5 days, respectively.
