After running a race, Laura is tracking how quickly her
heart rate decreases. If her heart rate at the end of the
race is 150 beats per minute, and she finds that it
decreases by 20 beats per minute every minute after the
end of the race, which of the functions below represents
her heart rate based on minutes after the race?
O h(x) = 20 + 35x
h(x) = 150 - 20x
○ h(x)
h(x)
= 20x + 150
