Derek works at Subway making $9.25 an hour.  The function d(x)=9.25x tells us how much money Derek makes after x hours of working.  What is the meaning of d(4)=37?

• After 4 hours of work, Derek makes $37.

• Derek needs $4 more to have $37 total.

• After working for 4 days, Derek makes $37 total.

• After 4 hours of work, Derek now makes $37 an hour instead of $9.25.

f(x) represents the amount of money in your bank account after 'x' months. Which notation below represents: The amount of money in your bank account after 3 months is more than the amount of money in your bank account after 4 months?

• f(3) = f(4)

• f(3) = 4

• f(3) < f(4)

• f(3) > f(4)
