Jasmine’s race time was 34.287 minutes. round her race time to the nearest 10th of a minute

Hi!

34.287 rounded to the nearest tenth is 34.290

This is because 7 is greater than 5, so we would round it to the cloest tenth that is slightly higher than 7. =)

34.3 minutes because if a number is higher than 5 it rounds up and in this case since the decimals are 2 tenths 8 hundredths and 7 thousandths. because the hundredths value is a number bigger than 5 you would round it up to 1 tenth making the tenths value 3

Do you need with the x value for the minimum? its always between the two intercepts for a parabola
