Question

Jeremy’s family wants to rent bicycles. The table shows the cost in dollars, y, of renting a bicycle for x hours.
x =1 2 3 4 5 6
y = 15 25 35 45 55 65

What type of function is represented?

exponential
quadratic
linear
logarithmic

Answer 1

Linear — the cost increases by a constant $10$ each hour (common difference), so it's a linear function. Equation: y = 10x + 5.
