Question

A state park charges $5 per car plus $1 per person as an admission fee. The total charged for a car with x people is f(x) = x + 5. How will the graph of this function change if the per car charge is changed to $8 per car?

Answer 1

Given: f(x) = x + 5

If this function changes to $8 per car then

The function: f(x) = x + 8

The concept of equation of straight line: y= mx + b

where b represents the y-intercept

In the equation above, the y-intercept changed from 5 to 8.

The graph will shift 3 units up
