Substitute your x and y into the equations x=1 y=3
Y = x - 2
3 = 1 - 2. Is not a true statement and is your answer

1hr is 60 min so
60÷15=4
45miles×2hrs=90
45÷4=11.25
90+11.25=101.25 miles
101.25 miles÷ 25 miles per gallon= 4.05 gallons
4.05 gallons× $2.75 per gallon= $11.1375
$11.1375= $11.14

Hello from MrBillDoesMath!

Answer:

Choice B: {1,2,4}

Discussion:

The range of the function is the set of "y" values shown in the table, which is 1,4,4,2. As sets do not contain duplicate elements, the range is {1,2,4). This is Choice B

Thank you,

MrB
