Yes it is a function because none of the x-values belong to 2 different y-values. The domain is -4, -3, -2, 0, 2, 3. The range is -3, -1, 0, 2, 3. The value of y when x=2 is -3 because when the x-value was 2 the y-value the point was on equaled -3.
In this problem, we have a pair of like terms in our <em>x</em> terms.
3x and -2x are like terms because they are exactly alike except for the coefficients or the numbers in front of the variables.
There are 45 students in total, and 9 of them have freckles. So you can say 9 out of 45 students have freckles. You can write this 3 ways.
9:45
9 to 45
(a) You would use the distance formula to get 80.
(b) You would use the midpoint formula to get (1,-5)
