How do you list -0.5, 3, and -4.2 from least to greatest

-4.2 is the least so that will go first

-0.5 will go after -4.2 because it is less than that number

then 3 will go last because it's the greatest number (it's a positive number.)

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
